1. 1.1 words and expressions
Objective: Students should be able to demonstrate they know the order of operations and how to apply it. They should know what a numerical expression is and how to write one.

2. Definitions Evaluate: Solve to get a numerical value.
Numerical expression: numbers and operations.
Ex: – 4
Verbal model: use math symbols and apply to words.
Key Words:
Addition: sum
Subtraction: difference
Multiplication: of, product
Division: quotient

3. Examples of verbal expression
Tell me what math you would use.
Product of
Increased by
Divided into
Decreased by
Write out as a math problem.
30 increased by 5
The product of 5 and 6
The difference of 10 and 7

4. Write as numerical expression –st.
Product of 41 and 2
17 more than 3.
Quotient of 20 and 2
Sum of 6 and 7

5. Definitions/Order Order of Operations: solve more than one operation.
Parentheses: ( ), { }
Exponents: x3, x2
Multiply: x / Divide: /
Add: + / Subtract: -
HELPER:
Parenthesis = Please
Exponents = Excuse
Multiply = My
Divide = Dear
Addition = Aunt
Subtract = Sally

6. Grouping Symbols / Examples
Kinds:
Brackets { }
Parenthesis ( )
Fraction bars /
Do in this order!!!
Note: have division need to rewrite.
Ex: 4 + 5
3 - 2
Write as (4 + 5) / (3 – 2)
40 – (52 – 2)
18 - 6

7. Teacher Examples 9 x 7 + 30 / 3 12 – 2 x 7 41 x (7 + 3) x 2
18 –

8. Student Example 4{15 – (2 + 5)} 7.8 + 2.2 7 - 5 5 (3) + 3(1.1)
5 (3) + 3(1.1)
5(14 – 32)

9. Wrap up
Any questions or concerns.
