Question

Write a number sentence and determine the sum for the shown model.

Answer 1

5 + -2 = 3.
Three is the sum because 5 is the highest number & is a positive. Therefore you keep the positive & subtract as normal. Making the answer 3.

Answer 2

5 + -2= 3

Explanation:

the answer is 3 because you have to make zero pairs. the 2 negatives and 2 of the positives make a zero pair, which makes 3 positive ones left so the final answer is 3
