Evaluate the Expression 3 + 7 = 10 10 x 3 = 30 7 x 3 = 21 3 +21 = 24

Objective SWBAT use the order of operations to simplify numerical expressions.

Section 1.1, Order of Operations Numerical expression consists of numbers and operations 9 + 8 4 - 9 5 ÷ 2 6(10)

Order of Operations – the rules established to simplify an expression involving more than one operation 10 ÷ 2 · 6 (4 + 7 · 6)²

1 2 3 4 PEMDAS Order of Operations Perform operations within grouping signs. ( ) parentheses, [ ] brackets, fraction bars 2 Evaluate powers. 3 Multiply and divide in order from left to right. 4 Add and subtract in order from left to right.

Simplify the Expression PEMDAS 18 - 2 · 4 18 - 8 10

Simplify the Expression PEMDAS 18 ÷ 2 · 4 9 · 4 36

3 POWER 4 the result of repeated multiplication of the same factor Remember this??? 4 Repeated Multiplication (Factors) 3 EXPONENT Words three to the fourth power BASE

Simplify the Expression ² PEMDAS 2 + 7 · 3 4 + 7 · 3 4 + 21 25

Simplify the Expression PEMDAS 14 + 6 Grouping symbol 12 – 7 (14 + 6) ÷ (12 – 7) 20 ÷ 5 4

Simplify the Expression ³ [2 x (4 + 4)] + 3 ³ [2 x 8] + 3 ³ 16 + 3 16 + 27 PEMDAS 43
