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
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 = 10 + 84 + 10 = 104 Width = 10 + 46 + 10 = 66 Total Cost = (9)(104)(66) = 61,776
Write this term in the vocabulary section of your Math Journal Numerical Expression = a collection of numbers, operations, and grouping symbols.
Evaluating Expressions 1.) Evaluate the innermost grouping symbol 1st and then work your way out. Ex: 12 + [(35 7) 2] (35 7) = 5 [5 2] = 10 12 + 10 =22
