Should I upload an image of the homework?

http://i.imgur.com/A2bEoQO.jpg

I know how to do a lot of it, I just don't know how to explain it.....

Someone please explain how I would start doing this

http://prntscr.com/87q3vq thats the explanation :=)

for 17 a just write *distributive property |dw:1440277416871:dw|

is**

just look at the 2nd sheet they gave you. :=)

http://i.imgur.com/bcRmUTL.jpg this one

would you multiply 1/2 times 2 or add ??

multiply

I have a question

i'm here please don't tag me on every comment
it creates lag:(

Ok so for C, would the problem in question be 1/2 x 1 + (1/2 x 2)t = 1/2 x 1 + 1 x t

And I would look at it like that in comparison to the other sheet?

Or would you find it in a different way?

these*

for C i would say simplify
bec they just divided 2 by 2 :=)

i forgot how to simplifyy

thats the problem

im 100% going to fail algebra II

nah you will not!!
think about good stuff
algebra is not just abt these properties :=)

this last one is called "inverse property of multiplication"

last one ??

is cancelling out 2's the associative property?

where on the sheet?

4th from the bottom

omg how do you even get that out of it

all i know about simplification is to combine like terms

and i dont even see that going on like what ????

do you see the line that says Inverse property of multiplication?

yes

the teacher said this was "review work" and I don't even know how do do this

like before she starts teaching us things and I don't even know the basics

Yes

Are they using PEMDAS in 17a to get to 17b?

what is the multiplicative inverse of 4/5 ? (what do you multiply it by so you get 1)?

we'll get to 17a in just a minute.

Do you have time to learn this now?

Yes

And I don't know what I'd multiply by 4/5

4/5 x 1/5?

you "flip it"

4/5 x 5/4?

20/20 = 1 ohh

but where did you get the 5/4 from

that is enough about the multiplicative inverse.
how far did you get answering your questions?

to 17b and I didn't really understand it

Ok I'll tag you when I get back

what is the difference between line 17a and 17b?

1/2 was multiplied into 2 and t so distributive property

1/2 x 2

the difference is this part
\[ \frac{1}{2}(2t) \text{ vs } \left( \frac{1}{2}\cdot 2 \right) t \]

Right I knew that but just didn't know how to explain it

do you see the property on your cheat sheet that shows "moving the parens" when multiplying?

Yes

Associative property

yes, specifically associative property of multiplication

what about b to c?

on 17

inverse property of multiplication?

no

Yes it does change

what changes?

nvm

what about c to d?

1/2 x 1 is 1 and 1 x t is 1

1/2*1 is not 1

i meant 1 x 1/2 is 1/2

yes, and that is an important property

I know how it works im just trying to find which property

look for 1 times "something" equals "something"

identify property of multiplication?

yes. thought it is spelled identity

omg im getting it

ready for Q 18?

Yes

what is the exact difference between the left and right sides of 18a?

switched around

are there alot of trolls like that? xD

yes, specifically when adding

so look for a property related to addition that shows "switching"

Is it associative property of addition?

associative is "where to put the parens"

commutative property of addition?

yes. they show a+b= b+a
and that shows the "switching around" that you noticed with 2+a and a+2

now for 18a to 18b
what is different?

Brackets are switched around

distributive property?

associative

of addition

are c and d identity property of addition?

what is the difference between line 18b and 18c ?

the addition in the brackets is added

be more "literal"
(2 + (-2)) turns into 0
do you see a property that shows that?

is 18c inverse of addition?

ok!

now 18c to 18d
a+0 becomes a

so would d be identity property of addition since its literally a+0

same as the cheat sheet

yes. adding 0 to anything does not change it.

Q19 looks almost the same as Q18

19a associative property of multiplication?

19a, what is different (the symbols) between the left side and the right side?

5 and n are switched

and be able to switch order is what property?

commutative?

yes, commute means switch
so here, commutative property of addition (same as in Q18a)

then i have no idea for 19b

now 19a to 19b
we "move around" parens. what property is "move parens"?

associative

inverse of addition?

notice the pattern is
(a+b)+c becomes a+(b+c)

associative property of addition?

19 b is associative prop of add
19 c is ?

omg i was looking at the wrong one

identity for 19c

of addition

what is different between 19b and 19c ?

(n + (-n) ) becomes 0
what property is that ?

inverse of addition

yes. 19C is inverse of addition
now what is different between 19C and 19D ?

5+0 = 5

identity property of addition

yes

now the difference between 19D and 19E ?

then 19e is inverse of miltiplication

yes. Is this making sense?

yes

Theres another side I did before I knew all this

Could you check it?

can you do Q20?

and I think so

http://i.imgur.com/bXgg5li.jpg Heres the other side

Heres for 20-
A- distributive
B- identity of multiply
C- inverse of addition
D- distributive

check 2,8,10,11

ok

20C and 20D are not correct.

Oh

what is the difference between 20B and 20C ?

3 is switched to the other side

and "switching" is what property?

itentity

identity of addition*

if you look on your cheat sheet identity of addition is a+0 becomes a

oh yeah

commutative of addition

yes, 20C is commutative of addition
what is different between 20C and 12D ?

associative property of addition

yes. the parens were changed

is 21a commutative property of addition?

what is different between 21 left and right ?

no its associative property of addition

yes

umm

write down the difference

multiplication of negative 1?

21A to 21B ?
k becomes 1*k

identity of multiplication

yes. notice we went "backwards" from k to k*1
but that is ok. these rules work both ways

what is different between 21B and 21C ?

then identify again?

write down the "before" and "after"

wait what

so for 21b i would put before identity of multiplication?

then after for 21c

yes, but just the part that is different

both of them are identity of multiplication?

(1*k + 1*k) becomes (1+1)*k

tell me how to write it XD I think I have the right answer

for 21b and 21c

Yes

what property is that?

identity of multiplication?

distributive

for 21c?

yes. we are going from (1*k+1*k) to (1+1)*k which is like (ab+ac) to (b+c)*a

im confused about c.5 to d

substitution to d

For 21c how does 2*1 go to 2(k+1)

finally
2*k +2*1 becomes 2(k+1)
that is the distributive property (backwards)

ok!

is 22a identity property of multiplication?

what is different between 22a left side and right side?

x is moved around

switched around? what property?

commutative

for mult.

Yes

now what is different between 22a and 22b ?

x is removed and brackets are added

notice the pattern
xA+xB becomes x(A+B)
?

Yes

and what property?

Distributive backwards

yes

22b to 22c . what is different?

is 22c associative property of multiplication?

The parentheses are moved in 22d

22c is associative property of addition
22c to 22d the change is (-1 + (-1) ) becomes 0

**(1+(-1)) becomes 0

Inverse property of addition?

yes

then 22d is identity property of addition

yes

thank you so much for helping me learn this!!

what about the other side?
