Example 1
 -5

Explanation:

–6 is the subtrahend.

Change the sign of the subtrahend and change the operation symbol to +.

–11 + 6

Add the integers. (Take note that the integers have different signs. So subtract the two numbers and copy the sign of the larger number).

11 – 6 = 5

Since 11 is greater than 6, copy the sign of the integer with 11.

The difference is –5.

Example 2
 7

Explanation:

–10 is the subtrahend.

Change the sign of the subtrahend and change the operation symbol to +.

-3 + 10

Add the integers. (Take note that the integers have different signs. So subtract the two numbers and copy the sign of the larger number).

10 – 3 = 7

Since 10 is greater than 3, copy the sign of the integer with 10.

The difference is 7.
