Answer 3

In basic arithmetic, when you add or subtract two like-signed numbers, the result depends on the sign of the numbers:

1. Positive + Positive: When you add two positive numbers, the result is positive. So, +a + a = 2a.

2. Negative + Negative: When you add two negative numbers, the result is negative. So, -a - a = -2a.

3. Positive + Negative: When you add a positive number and a negative number, you subtract their absolute values, and the result takes the sign of the number with the greater absolute value. So, +a - a = 0, and -a + a = 0.

So, in summary:

• +a + a = 2a
• -a - a = -2a
• +a - a = -a + a = 0
