Add using the number line. 8 + (-4) Drag and drop the word SUM to the correct value on the number line.

The answer is 4.

Step-by-step explanation:

Given problem,

8 + (-4)

Since, in the number line the numbers left to zero are negative and right to zero are positive,

When, we move towards a negative number then we move left side while when we move towards a positive number then we move right side,

Thus, the steps involve in the given problem are follow,

Step 1 : Find 8 on the number line,

Step : we have - 4, means we need to move left side 4 unit from 8,

Step 3 : the final position is 4.

Hence, 8 + (-4) = 4

Place "SUM" at 4 on the number line.

Step-by-step explanation:

8 + (-4) = 8 - 4 = 4

Adding a negative number is the same as subtracting its opposite. Adding - 4 is the same as subtracting 4.
