Question

When using the number line you represent subtraction of a negative number with an arrow going to the ______.

PLS HELP IM SO CONFUSED

Answer 1

When using the number line to represent subtraction of a negative number, you would represent it with an arrow going to the right (or in the positive direction).

For example, let's say you want to represent the following subtraction on a number line:

5 - (-3)

You can start at 5 on the number line and then move to the left by 3 units, since you are subtracting a negative number. However, instead of leaving the arrow pointing to the left to represent the subtraction, you can turn it around and point it to the right, which is the positive direction. This means that you end up at a point that is 8 units to the right of 0 on the number line, which represents the answer of 8.

So, the arrow would go to the right to show the subtraction of a negative number on the number line.

Answer 2

When using the number line, you represent subtraction of a negative number with an arrow going to the right. The direction of the arrow indicates the movement of the number line towards the positive side, which is the opposite of the direction of a negative number. Subtraction of a negative number is equivalent to addition of a positive number, so the arrow going to the right represents the addition of the absolute value of the negative number. For example, if you are subtracting -5 from 10, you can represent this on a number line by starting at 10 and drawing an arrow to the right that goes 5 units, ending at 15.
