Question

How do you evaluate `16+ ( - 1)`?

Answer 1

15

Explanation:

So there are a few scenarios you must learn.

1. A positive sign multiplied with a positive sign.
   `(+) * (+) = +`

2. A positive sign multiplied with a negative sign.
   `(+) * (-) = -`

3. A negative sign multiplied with a positive sign.
   `(-) * (+) = -`

4. A negative sign multiplied with a negative sign.
   `(-) * (-) = +`

In the question `16+(-1)`, you apply the second scenario. Both are the same and interchangeable.

Therefore, `16 + (-1) = 16-1 = 15`

Answer 2

The answer is `15.`

Explanation:

When you have a `+` and a `-` together, you subtract and take the sign of the number that is bigger.

`16 + (-1)`

`= 16 -1`

`=15`

So, the answer is `15.`

Answer 3

A = `16 - 1` = `15`

Explanation:

The only details you have to remember when performing operations such as these is the fact that when there is a `+` and a `-`, the `-`, will - generally - "overpower" the `+` and turn the operation into a negative. All the best!
