Answer 1

Hi! I'd suggest simplifying each side of each equation :)
For example, for the first one, what's 7 + (-10) ?

Answer 2

-3?

Answer 3

Great! And how about -13 + 17?

Answer 4

30

Answer 5

Not quite! Don't forget the minus sign in front of the 13!

Answer 6

oops 4?

Answer 7

That's it! :)

Answer 8

a. -3 < 4
