Described how to find the sums -4+2 and -4+(-2) on a number line

The answer to this question is given below in the explanation section.

Step-by-step explanation:

The number line helps in understanding the negative and positive numbers.

with the help of a number line, you can easily add and subtract positive and negative numbers.

As it is required to find the sum of -4+2 and -4+(-2) on the number line.

We know that

-4+2=-2

and

-4+(-2)=-6

now we want to know how to represent them on number line.

You know the number line, the center is the origin that is represented by zero, and the number that goes in the right direction are positive numbers and the numbers that go, in left direction are the negative number.

so first we point -4 at the left side of the origin of the number line. then the next number in this equation is +2 which means we have to move from -4 to two-point right on the number line, then we reach point -2 at the number line.

next is -4+(-2)

for this, we point at -4 on the number line, then the next sign is + that means we have to move forward but toward the left direction because of -2. as we left side two points on the number line from point -4 we will reach at -6. so -6 is the answer of this addition (sum).
