Answer:

  • 39, Obet is right

Explanation:

  • I guess the = should be ÷ or else it doesn't make sense.

Simplify in steps considering the hierarchy of operations:

  • 3 + 6 × {(15 + 9) ÷ 3 - 2} = Parenthesis
  • 3 + 6 × {24 ÷ 3 - 2} = Parenthesis, division
  • 3 + 6 × {8 - 2} = Parenthesis, subtraction
  • 3 + 6 × 6 = Multiplication
  • 3 + 36 = Addition
  • 39
