Order of Operations (G.E.M.D.A.S)

G.E.M.D.A.S. G “ ”= Grouping Symbols ( ), [ ] “ ”= Exponent “22” “ ”= Multiplication “6x8” “ ”= Division “9÷3” “ ”= Addition “7+5” “ ”= Subtraction “10-4”

What is G.E.M.D.A.S and why do we need it? G.E.M.D.A.S. is also know as the Order of Operations. Order of Operations is the order in which you perform mathematical operations to solve an equation.

STEPS 1st: Do what is inside of grouping symbol ( ) or [ ]. 2nd: Simplify Exponents. 3rd: Multiply or divide from left to right. 4th: Add or subtract from left to right.

GROUPING SYMBOLS “( )” , ”[ ] or { }” Used to group equations. Parenthesis ( ) Brackets [ ] or Braces{ } 6[100 - (5+3)] 6[100 - (8)] 6 [92] Answer: 552

Choose the proper way to solve the equation: xponents “22” 2 5 x 2 Choose the proper way to solve the equation: 2 = 4 4x5 = 20 Used to multiply the same number repeatedly. Exponent tells how many times a base number is multiplied to itself. 53 = 5x5x5 =125 2

ultiplication “x” 2 + 5 x 3 5 x 3 = 15 15 + 2 = 17 Answer: 17 Multiplication is just a faster way to add. Choose the proper way to solve the equation: 2 + 5 x 3 5 x 3 = 15 15 + 2 = 17 Answer: 17

ivision “÷” 12 4 + 2 12 4 = 3 3 + 2 = 5 Answer: 5 Division is splitting a larger number into smaller parts. Remember to check your division with multiplication.

ddition “+” (113 + 19) + 81 =? 113 + 19 = 132 132 + 81 = 213 It is tempting to want to solve addition first in an equation. Remember: only solve addition first if it is in parenthesis.

ubtraction ”-” 74 – (12 - 4) 12 – 4 = 8 74 – 8 = 66 Answer: 66 Subtraction is when you take away an equal or smaller amount from a number. You can check your subtraction with addition.
