Of course you don’t remember. Did you learn all operations?
Gertha I have a problem. We learned about integers in school today but I have absolutely no idea what we learned.
Integers is a special set of numbers comprising zero, positive numbers and negative numbers.
SIR WHAT ARE INTEGERS
Slide: 3
I think I do! Can we talk about multiplication and division now?
Sure! What do you know so far?
Okay so, in multiplication you multiply the numbers normally, but if they have the same signs the answer will be positive, and if they have different signs the answer is negative. Much simpler than addition and subtraction, right?
So I know that you multiply normally, but I don’t know what to do with the signs.

Since you found multiplication simple, you’re in luck because division follows the exact same rules! Obviously you divide not multiply, but the rest is the same!
Yes! Multiplication seems pretty easy! What about division?
YES. Okay, so tell me if I’m wrong: -7 x -8 = 56 and -7 x 8 = -56?
Nope, you got it right!

Precisely. Do you think you are ready for school tomorrow? You can review this with me before class if you want to.
Yay! Wait, before you leave, let me know if I'm good with division and addition too: -9 / 3 = -3 and -8 + -9 = -17?
No problem Debrah, anytime.
I think I’m ready, but yeah I want to review it tomorrow too. Thank you so much for the help Gertha, you are a great friend!

She said she would but I think she forgot me. Yeah I'll call her. OH MY GOSH I'M SO SORRY I DROPPED IT
So is your mom coming to pick you up? You can use my phone to call her if you need to.
Fine, bye.
You are #cancelled and no longer my friend. Leave please!
