Question

Can someone explain how the equation 27-(-5)-12 = 20?

Answer 1

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 2

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.
