This is an order of operations problem.


I remember this by using the mnemonic device: Pretty Please My Dear Aunt Sally


Acronym: PPMDAS

Steps

  1. Parentheses
  2. Powers
  3. Multiplication
  4. Division
  5. Addition
  6. Subtraction


Solve 52 (7-5)+2:


  1. Parentheses (7-5) = 2
  2. Powers 5 squared = 25
  3. Multiplication 25 x 2 = 50
  4. Division: none
  5. Addition = 50 + 2 = 52
  6. Subtraction: none


Answer 50 + 2 = 52
