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

P.E.M.D.A.S. “ ”= Parenthesis “()” “ ”= Exponent “2 2 ” “ ”= Multiplication “6x8” “ ”= Division “9÷3” “ ”= Addition “7+5” “ ”= Subtraction “10-4”

What is P.E.M.D.A.S and why do we need it? P.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. We need P.E.M.D.A.S because it helps us solve equations properly and always the same way. Remember: Calculate an equation in the wrong order and you will get the wrong answer.

arenthesis “( )” Used to group equations. Parenthesis can also be shown as brackets. ”[ ] or { }”. An example of an equation with parenthesis is: 6 (5+3) Choose the proper way to solve the equation: A. 6x5 = = 33 B. 5+3 =8 8 x 6 = 48 Answer:

xponents “2 2 ” Used to multiply the same number repeatedly. Exponent tells how many times a base number is multiplied to itself. 5 = 5x5x5 =125 An example of an equation using exponents is: 5 x 2 Choose the proper way to solve the equation: A. 2 = 4 4x5 = 20 B. 5 x 2 = = 100 Answer:

ultiplication “x” Use the table on the right to help you. Choose the proper way to solve the equation: x 3 A. 5 x 3 = = 17 B = 7 7 x 3 = 21 Answer:

ivision “÷” Division is splitting a larger number into smaller parts. An example of an equation with division in it is: Choose the correct way to solve the equation: A = = 2 B = = 5 Answer:

ddition “+” It is tempting to want to solve addition first in an equation. Remember: only solve addition first if it is in parenthesis. An example of an equation with addition in it is: Choose the proper way to solve the equation ( ) + 81 =? A = = 213 B = = 213 Answer: A or B

ubtraction ”-”. An example of an equation with subtraction in it is: 74 – (12 - 4) The proper way to solve this equation is: A. 74 – 12 = – 4 = 58 B. 12 – 4 = 8 74 – 8 = 66 Answer:
