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

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.

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!
