Solve the stuff in brackets first:- (-7 + 2) = -5 now solve the rest of the expression -5 * -4 = 20

(-7 + 2) * (-4) (-5) * (-4) Negative value multiplied by negative value yields positive value, that is -5 multiplied by -4 yields 20.

first () have higher precedence so things inside () run first (-7+2=-5) -5*(-4)=20 That's simple
