Answer: below ^-^

Explanation:

Our task is to simplify the following:


\sf{27-(-5)-12}

First, we will recall one of the integer rules that states:


  • \bf{a-(-b)=a+b}

We can now apply this rule to our problem:


\sf{27-(-5)=27+5=\boxed{\bf{32}}

We now have:


\bf{32-12

Subtract:


\bf{20}

Sure enough, you get 20.

This is how 27 - (-5) - 12 becomes 20.

Answer:

Please take a look at the explanation.

Explanation:

27-(-5)-12 = 20

A negative multiplied by a negative will be positive.

27 + 5 - 12 = 20

32 - 12 = 20

20 = 20

So, this one is True.
