Module 1. Mathematics

15.4 / 2 - 2 (4.6 - 15.7) =

  • -14.5
  • 26.5
  • 29.9

Explanation

The 2 directly before the bracket means multiply. First 4.6 - 15.7 = -11.1, then 2 * (-11.1) = -22.2, and 15.4 / 2 = 7.7. So 7.7 - (-22.2) = 7.7 + 22.2 = 29.9. Subtracting the negative product is what raises the total.
