Answer:

Because it is 3 units to the left of 2 on a horizontal number line

Explanation:

Given


2 + (-3) = -1

Required

Why?

The interpretation of the question is that:


2 + (-3) = -1

What is the result when 2 is shifted 3 units in the negative direction (i.e. towards the left)?

First, we have a horizontal to have the the following representation:

<.....-4 -3 -2 -1 0 1 2 3 4 5 ......>

Taking the positions of 2 and -1 into consideration,

<.....-4 -3 -2 -1 0 1 2 3 4 5 ......>

We can see that the distance between 2 and -1 is 3 units towards the left

In other words, -1 is 3 units from 2 in the left direction

Hence, option A answers the question
