Question

Determine the answer to (−5) + 4 and explain the steps using a number line

Answer 1

Hello,

The correct answer is -1.

(Drawing the number line)

Draw a number line on a piece of paper. Write a 0 in the middle. Then on the left side on the number line write the numbers -1 to -5. On the right side of the number line draw the numbers 1 - 5.

-5 -4 -3 -2 -1  0  1  2  3  4  5

(Finding the answer)

On the number line start at -5 and then move 4 spaces to your right and you will land on the number -1.

(Answer)

(-5) + 4 = -1

Hope this helps!!!!!! (:

Answer 2

A number line is just that a straight, horizontal line with numbers placed at even increments along the length. The answer to (−5) + 4 is 1 unit.

What is a number line?

A number line is just that – a straight, horizontal line with numbers placed at even increments along the length. It’s not a ruler, so the space between each number doesn’t matter, but the numbers included on the line determine how it’s meant to be used.

In order to find the answer to the (−5) + 4, we will use a number line. The integer negative 5 on the number line is represented on the left of the zero, which is 5 units away from zero.

While the integer positive 4 on the number line is represented on the right of the zero, which is 4 units away from zero.

Now, the sum between the two given integers is taken then it is the difference between two numbers on the number line. Since the -5 is 5 units away from zero, while +4 is 4 units away from zero. Therefore, the total distance between two integers is 1 unit.

Hence, the answer to (−5) + 4 is 1 unit.
