5. 1.4 Powers of 10 and Exponents
Expressions with repeated factors, such as 10 x 10 x 10, can be written by using a base with an exponent. The base is the number that is used as the repeated factor. The exponent is the number that tells how many times the base is used as a factor.
Ex: 10 x 10 x 10 = 10³ = 1,000 _

6. 1.4 Example
Hummingbirds beat their wings very fast. The smaller the hummingbird is, the faster its wings beat. The average hummingbird beats its wings about 3 X 10³ times a minute.
How many times a minute is that, written as a whole number?
Multiply 3 by powers of ten.
Look for a pattern.
3 X 10⁰ = 3 X 1 = __
3 X 10¹ = 3 x 10 __
3 x 1 0²= 3 x 10 X 10 = __
3 x 10³ = 3 x 10 x 10 x 10 = __
So, the average hummingbird beats its wings about ______ times a minute.

15. 1.8 Relate Multiplication and Division
You can use the relationship between multiplication and division to solve a division problem. Using the same numbers, multiplication and division are opposite, or inverse operations.

16. 1.8 Continued… For division,
You must find the inverse operation (multiplication) first in order to solve the problem.

17. 1.10 Numerical Expressions
A numerical expression is a mathematical phrase that has numbers and operation signs but does not have an equal sign.
Write an expression to match the words.
Greg drives 26 miles on Monday and 90 miles on Tuesday.
Lynda has 27 fewer fish than Jack. Jack has 80 fish.
Write words to match the expression.
Billy Bob has 17 fewer hot dogs than Jesse Joe. Jesse Joe has 34.
4. 6 x (12 - 4) Jeff has 12 birds than 4 flew away.Later on 6 times as many birds flew to Jeff looking for
, food.

18. 1.10 Your turn. Write an expression to match the words.
1. José shared 12 party favors equally among 6 friends.
2. Isabelle bought 12 bottles of water at $2 each.
3. Monique had $20. She spent $5 on lunch and $10 at the bookstore.

19. 1.11 Evaluate Numerical Expressions
To evaluate, or find the value of, a numerical expression with more than one operation, you must follow rules called the order of operations. The order of operations tells you in what order you should evaluate an expression
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction

20. 1.11 Examples and Your Turn Ex: 10 + 36 ÷ 9 Ex: 10 + (25 - 10) ÷ 5
Ex: 10³- (3 x 2) + 10
(4 + 49) - 4 x 10
(68 + 7)
Rewrite the expression with parentheses to equal the given value.
÷ value: 14
÷ value: 2

21. Distributive Property
Multiplying a sum by a number is the same as multiplying each addend by the number and then adding the products.
5 x (7 + 9) = (5 x 7) + (5 X 9)
One way (use addition)
Use addition.
8 x 59 = 8 ( ____ + 9)
= (____ x 50) + (8 x ___)
= ______ + ______
= ______
Second Way (use subtraction)
8 x 59 = 8 x ( __ - 1)
= ( __ x 60) - (8 x__ )
=______ - _______
= ___________
