-9-(-5) keep -9, change - to + and -5 to 5 -9+5=-4

Yes

yes

To solve the expression -9-(-5), we can follow these steps:

1. Start by simplifying the term inside the parentheses. When we have a negative sign in front of negative number (-), it becomes a positive number (+). So, -(-5) can be rewritten as +5.

2. Replace -9-(-5) with -9+5. The negative sign in front of the 9 remains unchanged.

3. Now, perform the addition -9+5. Since we have different signs (- and +), we subtract the smaller number from the larger number and use the sign of the larger number. In this case, 9 is larger than 5. So, 9 - 5 = 4. Since 9 is negative, the answer will also be negative.

Therefore, -9 - (-5) simplifies to -9 + 5, which equals -4.
