__Here are the 4 questions I will be doing.__

**2.**a) She used 15 zero pairs because it represents the equation for the red integer chips are positive and the blue integer chips are negative. This can also help her to get the product of the equation.

b) She should remove the negative integers as the equation in a statement is to remove 3 groups of (-5) which is 15 negative integer chips or (-15).

**7.**a) (+8) + (+8) + (+8)

b) (-6) + (-6) + (-6) + (-6) + (-6)

**11.**a) Remove 3 groups of (-2)

(-3) x (-2) = 6

b) Remove 3 groups of 3

(-3) x 3 = -9

**16.**a) 4 groups of 10

4 x 10 =

__40m__

b) 3 groups of 4

3 x 4 =

__12m__
