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

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

11−4⋅(−7)

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

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

=39

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
