Use PEMDAS rule in multi-operation expression.

1) 15 + I13 + 5 I/2
     Simplify the expression in parenthesis (absolute value) first:
           I 13 + 5 I = I18 I = 18 
     Divide 18 by 2 ⇒ 18/2 = 9
     Add 9 to 15 ⇒ 15 + 9 = 24
 
    15 + I18 I / 2
    = 15 + 9
    = 24   

2) 12 - 3(2)
     - Simplify 3(2) ⇒ 3 (2) = 6
     - Subtract 6 from 12 ⇒  12-6 = 6
  
     12 - 3(2)
      = 12 - 6
      = 6
