1. ORDER OF OPERATIONS

2. What is the correct method for solving numerical problems?

3. Parenthesis ( ) – solve math that is apart of the parenthesis first Multiply - Divide working left to right – which ever operation is first working left to right! Common symbols for multiplication ( ) x ● Common symbols for division ÷ and a fraction  (straight line ) / (slanted line) Exponents x 4 – solve math that involves exponents What are exponents? The value that indicates the number of times to multiply the given number Example: 5 6 = 5(5)(5)(5)(5)(5) NOT 5(6) ! Add – Subtract working left to right – which ever operation is first working left to right!

4. Practice Problem 1 60 - 4(6 - 2)+2 3 + 2

5. Practice Problem 1 60 - 4(6 - 2)+2 3 + 2 Parenthesis ( ) 60 – 4 (6 - 2)+2 3 + 2 60 – 4 (4)+2 3 + 2 Exponents x 4 60 – 4 (4)+2 3 + 2 60 – 4 (4)+8 + 2 Multiply –Divide 60 – 4 (4)+8 + 2 60 – 16 + 8 + 2 Add – Subtract 60 – 16 + 8 + 2 44 + 8 + 2 = 54

6. Practice Problem 2 (7 - 4) 2 + 4 ● 21 ÷ 3 – 2

7. Practice Problem 2 (7 - 4) 2 + 4 ● 21 ÷ 3 – 2 Parenthesis ( ) (7 - 4) 2 + 4 ● 21 ÷ 3 – 2 (3) 2 + 4 ● 21 ÷ 3 – 2 Exponents x 4 (3) 2 + 4 ● 21 ÷ 3 – 2 9 + 4 ● 21 ÷ 3 – 2 Multiply –Divide 9 + 4 ● 21 ÷ 3 – 2 9 + 84 ÷ 3 – 2 Add – Subtract 9 + 28 – 2 37 – 2 = 35 9 + 84 ÷ 3 – 2 9 + 28 – 2
