    EIGHTY FIVE
    7 × ( 4 + 3 2 ) 6
    7 * (4 + 3 ** 2) - 6
    7 * (4 + 3 ** 2) - 6
        = 7 * (4 + 9) - 6
        = 7 * 13 - 6
        = 91 - 6
        = 85
    
    FIFTEEN
    8 + ( 3 × 2 2 ) 5
    8 + (3 * 2 ** 2) - 5
    8 + (3 * 2 ** 2) - 5
        = 8 + (3 * 4) - 5
        = 8 + 12 - 5
        = 20 - 5
        = 15
    
    SIX
    12 ÷ ( 2 + 4 ) × 3
    12 / (2 + 4) * 3
    12 / (2 + 4) * 3
        = 12 / 6 * 3
        = 2 * 3
        = 6
    
    TWENTY ONE
    5 + 2 × ( 3 2 1 )
    5 + 2 * (3 ** 2 - 1)
    5 + 2 * (3 ** 2 - 1)
        = 5 + 2 * (9 - 1)
        = 5 + 2 * 8
        = 5 + 16
        = 21
    
    FOURTEEN
    6 × ( 2 + 3 ) 4 2
    6 * (2 + 3) - 4 ** 2
    6 * (2 + 3) - 4 ** 2
        = 6 * 5 - 4 ** 2
        = 6 * 5 - 16
        = 30 - 16
        = 14
    
    NINE
    9 + 3 × ( 8 2 3 )
    9 + 3 * (8 - 2 ** 3)
    9 + 3 * (8 - 2 ** 3)
        = 9 + 3 * (8 - 8)
        = 9 + 3 * 0
        = 9 + 0
        = 9
    
    TWELVE
    15 ÷ ( 3 + 2 ) × 4
    15 / (3 + 2) * 4
    15 / (3 + 2) * 4
        = 15 / 5 * 4
        = 3 * 4
        = 12
    
    TWENTY TWO
    7 × ( 5 3 2 ) - 6
    -7 * (5 - 3 ** 2) - 6
    -7 * (5 - 3 ** 2) - 6
        = -7 * (5 - 9) - 6
        = -7 * (-4) - 6
        = 28 - 6
        = 22
    
    FOURTEEN
    ( 8 + 2 ) × 3 4 2
    (8 + 2) * 3 - 4 ** 2
    (8 + 2) * 3 - 4 ** 2
        = 10 * 3 - 4 ** 2
        = 30 - 16
        = 14
    
    TWENTY
    10 ÷ ( 5 2 ) × 6
    10 / (5 - 2) * 6
    10 / (5 - 2) * 6
        = 10 / 3 * 6
        = 10 / 3 * 6
        = 60 / 3
        = 20
    


    Topic Intro and Notes

    This puzzle uses some examples of complicated order of operations math problems. involving a mix of addition, subtraction, multiplication, division, parentheses, and exponents. What makes them a puzzle is how easily a wrong answer can be found IF the calculations aren't performed in the correct order. Remember to follow the order of operations (PEMDAS/BODMAS) to solve them correctly. Enjoy!
