The document contains examples of arithmetic, relational, and logical expressions and equations for evaluation and solving. Parentheses are used to override the order of precedence in expressions, such as (3 + 7) * (9 - 2) = 70. Relational examples include evaluating if (5 + 2) + (-5 + 5) >= 77 and solving (3 - 2 * 5 * 2) != 125. Logical examples are 1 && 0 || (1 && !0).
