2
What’s the answer? 6 + 4 x 4 – 3

3
Order of Operations Hopefully you remember this: BEDMAS Brackets, Exponents, Divide, Multiply, Add, Subtract

4
B – Do the operations in brackets first E – Next, evaluate any exponents D M A S Then, divide and multiply in order from left to right Then, add and subtract in order from left to right

5
Brackets Just be aware brackets can look like any of these.

6
Exponents This will be our next unit, so we will just review the basics This is what you should know already: 3 2 Exponent Base Power 3 is the base 2 is the exponent 3 2 is the power 3 2 is a power of 3

7
Exponents Remember that 3 2 means that we have 3 units by 3 units AKA 3 x 3 = 9 3 3 3 x 3 = 3 2 = 9 9 is a square number

8
Exponents 5252 = 5 x 5= 25 5 5

9
Watch your negatives With rationals we have to be careful with negative numbers. With brackets (-4) 2 = (-4)(-4)= +16

10
If there are no brackets…

11
With decimals (0.5) 2 = (0.5) x (0.5)= 0.25

12
B – Do the operations in brackets first E – Next, evaluate any exponents D M A S Then, divide and multiply in order from left to right Then, add and subtract in order from left to right

13
Example 1 Brackets first. Then evaluate the power Then multiply Add

14
Subtract in the brackets first Use a common denominator of 8 To divide, multiply by the reciprocal of -5/16 Example 2

15
Example 3 The formula converts temperatures in degrees Fahrenheit, F, to degrees Celsius, C. What is 28.4°F in degrees Celsius? Substitute F = 28.4 in the formula SOLUTION

16
Homework Page 140-142 3, 4, 7, 11, 12

17
Now with Rationals

18
A harder example
