Question

Which number line shows the solution to 5 + (−5)?

A number line is shown from negative 10 to 0 to positive 10. There are increments of 2 on either side of the number line. The even numbers are labeled on either side of the number line. An arrow pointing from 0 to negative 5 is shown. Above this, another arrow pointing from negative 5 to negative 10 is shown. A vertical bar is shown at the tip of the arrowhead of the top arrow.

Answer 1

An arrow pointing from 0 to negative 5 is shown. Above this, another arrow pointing from negative 5 to 5 is shown. A vertical bar is shown at the tip of the arrowhead of the top arrow.

Explanation:

This may mean that 5-5=0 and that the negative 5 is arrowed to show the direction 0 to -5 and the 0 to 5 shows the answer.

Answer 2

A number line is shown from negative 10 to 0 to positive 10. There are increments of 2 on either side of the number line. The even numbers are labeled on either side of the number line. An arrow pointing from 0 to 5 is shown. Above this, another arrow pointing from 5 to 0 is shown. A vertical bar is shown at the tip of the arrowhead of the top arrow.

Explanation:

The answer is A number line is shown from negative 10 to 0 to positive 10. There are increments of 2 on either side of the number line. The even numbers are labeled on either side of the number line. An arrow pointing from 0 to 5 is shown. Above this, another arrow pointing from 5 to 0 is shown. A vertical bar is shown at the tip of the arrowhead of the top arrow because 5 + (-5) is the same as 5 - 5, which equals 0, which is what the arrow points to in A number line is shown from negative 10 to 0 to positive 10. There are increments of 2 on either side of the number line. The even numbers are labeled on either side of the number line. An arrow pointing from 0 to 5 is shown. Above this, another arrow pointing from 5 to 0 is shown. A vertical bar is shown at the tip of the arrowhead of the top arrow.
