Question

Write an addition equation or a subtraction equation (your choice!) to describe the diagram

Answer 1

Answer:  -3 + 4 = 1

==================================================

Explanation:

We start at the bottom layer.

That arrow on the bottom layer goes from 0 to -3. In short, it represents the number -3.

The upper arrow moves from -3 to +1 or simply 1. This is a distance of 4 spaces. So we add on 4.

Overall, this diagram represents -3+4 = 1
