1. The document provides instructions and examples for lesson 63 on order of operations without using a calculator. It includes an assignment to complete a set of problems without checking answers and examples to simplify expressions using parentheses, brackets, and braces. 2. Warm-up questions ask students to simplify numerical expressions and find the area of a figure. Lesson 63 then reviews that symbols of inclusion like parentheses must be solved innermost first when multiple sets are present in one problem. 3. Several multi-step problems are presented as examples for students to simplify using order of operations, including those with fractions, absolute values, grouping symbols and nested sets of inclusion markers.

Lesson 63 Warm-Up:
1) Simplify: 3(8) - (5)(2) + 10 2
2) What is the area of this figure: 4 1/2
(dimensions are in feet)
4
6
2
3) Simplify: 12 1/2 x 4 4/5 x 3 1/3
4) Divide 456 by 28 and write the answer as a mixed number.
5) Compare: 2-3 2-2

Lesson 63
*FYI...remember...symbols of inclusion could be parentheses ( ),
brackets [ ], or braces { }
...and when we have more than one of these within a problem, we
must start with the innermost set first!
