13. Write these terms in the vocabulary section of your Math Journal
Sum = The answer to Addition
Difference = The answer to Subtraction
Product = The answer to Multiplication
Quotient = The answer to Division

14. Area Example 2 Cost per Sq. Foot 1.) Calculate the area in sq. feet
2.) Multiply the area by the cost per sq. foot
Length = = 104
Width = = 66
Total Cost = (9)(104)(66) = 61,776

15. Write this term in the vocabulary section of your Math Journal
Numerical Expression = a collection of numbers, operations, and grouping symbols.

16. Evaluating Expressions
1.) Evaluate the innermost grouping symbol 1st and then work your way out.
Ex: [(35  7)  2]
(35  7) = 5
[5  2] = =22
