Question

Use the number line and add the following integers:

$10+\left(-7\right)$

Answer 1

Adding numbers using number line:

Step 1: Choose the first integer as the starting position on the number line:

Since, we have to add $-7$ to $10$, we will begin from $10$ on the number line.

Step 2: Move toward the right if the second integer is positive or left if the second integer is negative:

$-7$ is a negative integer. So, we will move toward the left direction.

Step3: Move as many steps as the second integer:

We will move $7$ steps to the left of $10$.

We reach $3$.

Hence, $10+\left(-7\right)$$=3$.
