My calculator is broken. The "+" key works correctly,but whenever I try to compute a-b, the calculator performs b-a instead. What answer does mny calculator compute for the expression ((7-10)+3)-5? Thank you!

((7-10)+3)-5 ---> (10-7) + 3) - 5)

= (-3+3) - 5 ----> (3-(-3)) - 5
= 6-5 ----------> 5-6
= -1

To find the solution using your calculator, let's break down the expression step-by-step:

1. First, calculate 7 - 10 using the "+" key:
7 - 10 = -3

2. Next, add 3 to the result obtained in the previous step:
-3 + 3 = 0

3. Finally, subtract 5 from the result obtained in the previous step:
0 - 5 = -5

Therefore, your calculator should compute -5 for the expression ((7-10)+3)-5.

To determine the answer your calculator computes for the expression ((7-10)+3)-5, we need to follow the order of operations and understand how the calculator is performing the subtraction operation.

In this case, your calculator is performing the subtraction operation by changing the order of the numbers. Instead of computing a-b, it is computing b-a. So, when you input (7-10) into your calculator, it will compute (10-7) instead.

Let's break down the expression step by step:

1. (7-10): Typically, this would evaluate to -3. However, since your calculator computes b-a, it will evaluate this as (10-7) which results in 3.

2. (3+3): Now, we add 3 to the result of the previous step, which is 3. This gives us 6.

3. (6-5): Finally, we subtract 5 from 6, resulting in the final answer of 1.

Therefore, your calculator will compute the expression ((7-10)+3)-5 as 1.
