The document provides examples of simplifying expressions with nested symbols of inclusion such as parentheses, brackets, and braces. It notes that when multiple levels of symbols are present, the innermost symbols should be simplified first working outwards. Six examples are given with no calculator to practice this concept.

1. 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!

2. Lesson 63 Examples: [No calculator]
Simplify.
A) 100 - 3[2(6 - 2)]
B) 30 - [40 - (10 - 2)]

3. C) 10 + 9 8 - 7
6 5-4-3+2
D) 1 + 2(3 + 4) - 5
10 - 9(8 - 7)

4. E) 12 + 3(8 - |-2|)
F) 100 - [20 + 5(4) + 3(2 + 40)]
