Orders of Operations 8/4/2017

Order of operation Simplify expressions using the order below. If grouping symbols, parenthesis/brackets, are present simplify expressions within those first, starting with the inner most set first. Evaluate exponential expressions. Perform multiplication or division in order from left to right. Perform addition or subtraction in order from left to right.

PEMDAS Parenthesis Exponents Multiplication Division Addition Subtraction Please Excuse My Dear Aunt Sally

Helpful hints 3+3(5+3) 3 2 +1 Be careful when evaluating exponents 3∙ 4 2 (3∙4) 2 If a fraction bar exists simplify the numerator first then the denominator 3+3(5+3) 3 2 +1

Examples 2+ 5−2 + 4 2 5 6− 3+2 −24

Due Today Using the acronym PEMDAS create a new phrase to help you remember the Order of Operations. Create a minimum of 5 examples of problems where you would need to use the orders of operations.
