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 · 2 when c = 1 results in 9 · 1 · 2 = 18.
Evaluating 3b ÷ 5 when b = 8 results in 3 · 8 ÷ 5 = 24/5.
Evaluating v³ ÷ v when v = 8 results in 8³ ÷ 8 = 64 ÷ 8 = 8.
Evaluating (c · c)² when c = 2 results in (2 · 2)² = 4² = 16.
