Exponents and Order of Operations

2. Exponents
A shorthand way to show how many times a number, called the base, is multiplied times itself, called the exponent / power.
be = b * b * b * b …

3. Example
Simplify 35

4. Example
Simplify 43

5. Example
Simplify 27

6. Order of Operation
A collection of rules that tells us which procedures to perform first in order to evaluate a given mathematical expression.
Rules
Addition, Subtraction, Multiplication, Division, Parentheses and Exponents

7. Order of Operations
P E M D A S

8. Example Simplify using order of operations,
(one step per line per point)

9. Example Simplify using order of operations,
(one step per line per point)
28 ÷ 7(2) – 3

10. Example Simplify using order of operations,
(one step per line per point)
[ ( * 2 / 5 ) – 9 ]

11. Example Simplify using order of operations,
(one step per line per point)
10 - ( 4 * 2 – 6)² - 2(3)

12. Example Simplify using order of operations,
(one step per line per point)
