Question

How do you simplify `11 - 4* (-7)`?

Answer 1

When we see an expression like this, we follow the correct order of operations:

Parentheses>Exponents>Multiplication and Division>Addition and Subtraction (PEMDAS)

`color(blue)(11-4*(-7)`

`= 11 - (-28)` (We performed the Multiplication first)

`= 11 +28` (And then the Subtraction of `-28` from `11`)

`color(blue) (= 39`

Answer 2

Multiplication is done before addition or subtraction so
do the multiplication first
`4*(-7) = (-28)`
and therefore
`11-4*(-7)`
`= 11- (-28)`
`= 11+28`
`= 39`
