Chapter Two:Combining like Terms and the

Babysitter: You have to go inside and do you're homework before you're parents get home!

Little Girl: But I don't understand how to.

Little Girl: explain it to me now and then I'll go inside and do it all by my self.

Babysitter: fine but you have to go do it right away.....okay??

Little Girl: fine

Babysitter: okay then, what are you learning?

Little Girl: we are learning about combining like terms and distributive property. We have two questions the first one is n + 3 minus 5 n + 12 .

Babysitter: oh this will be easy. Okay, what do you think the answer is?

Little Girl: well, from what i know i think the answer is negative 6 n + 15.

Babysitter: okay, let's go through this first you would combined the like terms.

Little Girl: that would be n and negative 5 n in brackets and three and twelve in brackets.

Babysitter: good now only one thing can come out of both brackets, so what is n minus 5 n?

Little Girl: ummmm.... negative 4 n ?

Babysitter: good that's right, now what is three plus twelve?

Little Girl: well thats easy fifteen.

Babysitter: so the answer would be negetive 4 n plus fifteen. so the only thing you did wrong was you instead of taking away 5 n you took away 6 n from n.

Little Girl: Oh thanks.....now the second question is 2 + 4 then in brackets 3 n + 8 and i think the answer is 12 n + 10.

Babysitter: this one is a little different first you have to add 2 and 4

Little Girl: that's 6

Babysitter: okay now we go 6 times 3 n

Little Girl: ummm....... 18 n

Babysitter: now what is 6 times 8?

Little Girl: that's 48

Babysitter: okay, so the answer is 18 n + 48

Little Girl: oh well, that is much easier then i thought thanks I'll go do my home work now

Babysitter: you're welcome :)

I really liked how you did yours with the colorings and how you placed it. I suggest you put the type of poem it is so we know how many syllables are going to be there. The rest is good and i understand it. Keep up the good work.
