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

Answer 1

Roman Alvarez

The answer is #15.#

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.#

So, you need to become familiar with a few scenarios.

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

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

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

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#

A = # 16 - 1# = #15#

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!

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
