Question

How do you evaluate `5- 6^ { 2} - ( - 5)`?

Answer 1

`-26`

Explanation:

start by order of operations. `6^2=36`, so now you have:

`5-36-(-5)`, and anytime you have a minus next to a negative number it becomes positive, so this gives:

`5-36+5`

Now the final step gives `10-36` which equals `-26`

Answer 2

`-26`

Explanation:

Use the order of operations.

There are no expressions inside parentheses (`-5` doesn't count since it's just a number by itself). So, the next step is to solve the exponents.

`5 - color(red)(6^2) - (-5)`

`5 - color(red)36 - (-5)`

Now, all that is left is addition and subtraction. Note: subtracting a negative number is the same as adding the positive form of that number, so we can change the `-(-5)` to a `+5`.

`5 - 36 - (-5)`

`5 - 36 + 5`

`-26`

So this expression equals `-26`.
