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)114(7)

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

= 11 +28=11+28 (And then the Subtraction of -2828 from 1111)

color(blue) (= 39=39

Multiplication is done before addition or subtraction so
do the multiplication first
4*(-7) = (-28)4(7)=(28)
and therefore
11-4*(-7)114(7)
= 11- (-28)=11(28)
= 11+28=11+28
= 39=39
