Module 1. Mathematics

(6 - 2) - (6 - 9) / (-3 + (-3))

  • 3 1/2.
  • 4.
  • 4 1/2.

Explanation

Following order of operations, work the brackets first: (6-2)=4 and (6-9)=-3, with the denominator (-3+(-3))=-6. Division comes before subtraction, so (-3)/(-6)=0.5, giving 4-0.5=3.5, or 3 1/2.

Isn’t this - 7/6?
