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

May 5, 2017

15

#### Explanation:

So there are a few scenarios you must learn.

1. A positive sign multiplied with a positive sign.
$\left(+\right) \cdot \left(+\right) = +$

2. A positive sign multiplied with a negative sign.
$\left(+\right) \cdot \left(-\right) = -$

3. A negative sign multiplied with a positive sign.
$\left(-\right) \cdot \left(+\right) = -$

4. A negative sign multiplied with a negative sign.
$\left(-\right) \cdot \left(-\right) = +$

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

Therefore, $16 + \left(- 1\right) = 16 - 1 = 15$

The answer is $15.$

#### Explanation:

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

$16 + \left(- 1\right)$

$= 16 - 1$

$= 15$

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!
