alright so that someone is called variables and expressions writing verbal expressions for algebraic expressions and vice versa so keep out and that way you can highlight on the vocab sheet if you've already did we already defined as work expression on that vocab sheet if you didn't then you need to put it in your notes if we did then you can highlight it on your phone Anna might want to change your wording or add an example or something like that was quite a trolls Ms first lesson this actually is not one that's on the vocab street but do you have your vocab sheets with you ever can out so that you can sync remember there's going to be a quiz on the vocab at the end of the chapter so as well today's vocabulary terms in the lesson it's going to be nicer for you if you have your vocab stayed out and you can kinda add on a picture or an example or change the wording on your sheet to help you better understand that Trump expression hello is not one of the whatever 18 things that are on here and or products numbers and variables so sums added or and or products multiplying numbers and variables then they have sample of a algebraic expression anything about the sum and product of numbers Wichita variable in there so we can call it one plus two a  separate algebraic expression. The sum add one and the product of two a  head family Harbor which variable is on the bottom of your vocab list on the bottom of the second side so if you want to highlight. add or change anything or expression 1/10 d the letter D is called variable  Saudi is the variable of that expression and adverb variables are symbols used to represent unspecified numbers or values any of that are Maybe ghost is available so you can use T you can use W you can use at they just chose the for this particular example and we can watch tape on a value like to we would substitute that value in and they would take .1 x 2 to get to  it's about substituting the Value Inn in evaluating the expression alright these are all examples of terms  Robin turn on such as well done at the bottom  Letterman is it is an expression excuse me a chain maybe a number a variable or a product or quotient of numbers and variables so you only have a product song  also this is one term and this is one term to watts is a Tome of that song and 4 is a term of that song Hair three is a charm  LG over what is a term she is a term she is a term cure for CD is a term 3 10 is a term Hazel terms again can be a number like Fair  lost my place a variable y p or two for a product to Rex work wasn't 0% add numbers and variables the factors are the qualities that are they multiplied so the factors of 2 are too and acts the factors of this product that remembers that you're buried as the a variable that are being multiplied those are the factors  so the factors of for cbr4 K & D what are the factors of 3 mm Play Eminem famous Tacos on here light-up see factors on there so make sure you get that written in for the other ones I can have variables and terminal you could like those down and just say refer to VOC Aber some kind of did you know it's already on your vocab  so factors with Mod on the been captured they are the quantities that you are multiplying the product the result is the products of the result of those qualities and multiplied is called the product search what is the product of 2 and X Pichu in the product of pmq first CD is what of for C & D you get the idea the product is the results of the factors that are multiplied raised. Or set of parentheses is often used to indicate a product so I used have a raised. Between p and Q  I guess I didn't use parentheses up here but you could put parentheses and that also named will multiply 3 by my aunt's you can use a raised dog or parentheses Meadowvale not using anymore a taxi I don't use the old school accident okay because these acts as a variable so it's confusing can you writing apps on writing the most creation symbol so your body is the various. Or the parentheses from here on out warmest time without highlighted vocab and then they just had two examples  an expression like s2bn is called a work  access called the base from Annie the exponent the power on overtime list so you can save your furniture Go tablets if you like  or you can but I would also right here and if you want to write something in your notes about it you can and then exponent I don't see exponent on there cyberpower is asked to be on that whole expression there is called a power the bay is the parts  that you were taking to the exponent the expanded the number of times the base is used as doctor so for example if we have five to the second that means you better * 2 * so sometimes we get a little Hasty and want to take 5 x - 10 minutes later than 5 side is 25 so be careful  it's not five times to its 5 * 552 * patzeria chewables number down this is a short lesson rainbow my best friend of mine and then I'll give you guys a new try so you have to watch and learn and help me write a verbal expression your table is going to come in today they want us to write a verbal expression describing 3 x to the fourth adding subtracting multiplying dividing there that's fine that's a good word to use when you multiply product product is probably the best most widely used formality for multiplication so they're doing the product of what free ant Singapore power  almost not just one way to do this at 7:30 a.m. 3 times x to the power so they wrote it differently but it's little both correct so it's not one answer cuz words to write down for each of these so you have a lot of options here what a b for the sum and product cancel we have like 5 times 3 to the 4th power plus 16  today in the Bank Florence free times to the second power so there's a total of 16 so they said the same thing as we did except for they have a typo this was second power in its not  alright here's Yours Like The Bagel expression for a Ambi this is your check under one extra Grampa one whenever you want to talk what's tomorrow weather LA I'm not going what it is because then you can just write what I say struggling with alright I volunteer for letter A bond Eye Center what is 16 * you to the second power minus three product and times can but you don't need them both if you say the product of 16 what did you say YouTube did you say okay so you can just put the Prada 15 and we'll go do something else besides the second power squared the second power sign I'm just sorting out other options and so the product of 16 and you squared War YouTube what color is fine I just wanted to point out that you could say squared when you take something to the second power the same thing as growing it and then -3 Barbie furniture Amelia okay females do something a little different. but that sounds good I'm wondering this one's a little tricky because I'm okay maybe have a murder rate hose again they had  how come a Plastics containment divided by 7 Paramount Staffing call Rangers crest Russian 65% the product of 60 divided by 7 Okay so how do we specify what were taking this time of these two things because the way that I just wrote what they sad but all these getting up the same results as  so do you need to start with the sum of  what Hathaway and the quotient of 60 and 7 because that is what this is this when you say when you just move straight across review order of operations what would you do first okay  mmm do your 6 times be so would you get this evening to get the same results so that so the way I would have been there if I would have went into some of would have a one half of a and the product of 64 equation 6 * b + 7 Basilica parts 6 times and 7 technically come out to be the same if you will just substitute values in and use your order of operations I wanted to talk that out myself out loud cuz I was thinking that while you guys were working it okay II example they're going to give us the verbal expression I prefer to do it this way they gave you just write the algebraic so I'm Number 2 more than 6 that's all you have to do on me  Flutterby cost of 10 less than the product of 7 and 1/2 the most confusing cuz when you read from left to right my son kids will write 10 - 7 of 7 and up is that correct no way to do that  yes what are the 10 West Ranger taking 10 from the product of 7 and F so most of the time by the time you reach algebra you already over that hump by when you first and verbal Expressions most kids want to take 10 - so I just wanted to make sure everybody is on the same page again most of you are over that Hurdle from 7th or 8th grade but if you want go get there 10 last name to take 10 from 7 and 1/2 paid volume v two-thirds of you don't even need a symbol that you could put away. You could put Prince's you could just leave it 2/3 feet alright here's your last  check understanding  call should be able to whatever you want to call it  robot the product of Pi and 6 as an algebraic expression and 1/3 BofA  yeah but there's other ways to present first one try quivering like they're different products registration math expression 266 The Flash open confidence today right and Blaze going to get Addie today  alright what's Saturday look like volunteer volunteer Bryan 66 P you can put it on in between if you want Craigslist Quad Cities that you don't need that during the right something different but you right  P6 okay you could put p insects and you can puppy six button algebra 6 is called the coefficient is today in front the variable so yes technically be two things mean the same thing but this is beef formal way of writing it in algebra how do I if you have the fraction 2/4 we should really reduce its 1/2 it's just a technicality so this play the most appropriate way thanks for volunteering I'm able to put a. Princess you put it on so then you don't need it. When you're multiplying okay I'm going to. There you can put parentheses around the A and they do something different the area a mercenary is the area of something so  who wouldn't want to square it then you would be swearing the air okay is there anybody do anything Kenny right this  one-third is not home so not really buggy rides a / 3 what's 1 * a  isn't that equal to 8/3 those are the same thing okay so either one of those would work do you put the variable behind the coefficient oh okay that's proper technique  rights federal ID there's a sneaking third example down here I lied sorry Sarasota Roman to mr. Martinez where there's 250 keychains athletic teams logo and 500 pencils printed with its water dress  right now generic expression that represents the cost recorder  what KD the car okay so the cost of a keychain assemble at BK so there's 550 keychains baby right turn in 50K Star Dental Center classifications right  plus it's getting 500 pencils that make hot water call the cost of a pencil search 150 x k k with the price of a keychain + 500 * P 500 pencils and P is the price per pencil  so that would be the expression last one  so extra example 3 you try to read it to Katie Bay 40 pastries and makes coffee for 200 people Freddy pastries is there anything on Indian pastries Ang batas a cartoon for children football  hey write a algebraic expression to represent the cost of the situation 40 pastries and 200 copies  relatable for the price of a pastry and you needed for the price of a coffee  she makes 40 pastries and serves 200 copies 40 pastries and 200 face yes volume expression to represent the cost of the situation how much does it cost Reggie White Chris 40 40p + 200 C flower for real.
