Study Notes
Evaluating Expressions
- The expressions are presented as mathematical problems with variables like a, b, c, u, v, x, y, z.
- Each expression has a value assigned to each variable.
- Solving the expression requires plugging the value of the variable into the expression.
- These expressions need to be solved in a specific order:
- Parentheses first, then exponents, followed by multiplication and division (from left to right), finally addition and subtraction (from left to right).
Example Expressions
- Evaluating
9c · 2whenc = 1results in9 · 1 · 2 = 18. - Evaluating
3b ÷ 5whenb = 8results in3 · 8 ÷ 5 = 24/5. - Evaluating
v³ ÷ vwhenv = 8results in8³ ÷ 8 = 64 ÷ 8 = 8. - Evaluating
(c · c)²whenc = 2results in(2 · 2)² = 4² = 16.
