Question

Perform the indicated operations. (-3)-(-8)-(+3)+(-9)

Answer 1

The result of the operation ((-3)-(-8)-(+3)+(-9)) is -7. Subtracting a negative number is the same as adding, and subtracting a positive is the same as subtracting. The operation can be broken down into steps to simplify.

Step-by-step explanation:

To perform these operations, it's important to understand how subtracting integers works. Subtracting a negative number is the same as adding, and subtracting a positive is the same as subtracting. So, we can rewrite the equation as follows: (-3) + 8 - 3 - 9. Now we add and subtract from left to right: 5 - 3 - 9, which gives us 2 - 9, therefore the answer to the question (-3)-(-8)-(+3)+(-9) is -7. The number 7 results from 2 subtracting 9. Hence, the operation can be broken down in an arithmetic progression to simplify:

1. -3 - (-8) = 5
2. 5 - (+3) = 2
3. 2 - (-9) = -7
