Evaluating expressions
Printable practice with an answer key the engine computes, at three levels, in as many versions as you need.
Problem types
- ax + b at a positive x: Evaluate 3x + 5 when x = 4.
- ax + b at a negative x: Evaluate 4x + 7 when x = −3.
- b − ax at a positive x: Evaluate 8 − 3x when x = 2.
- b − ax at a negative x: Evaluate 8 − 3x when x = −2.
- the letter inside parentheses: Evaluate 4(x − 3) when x = 5.
- x over a number: Evaluate x/2 + 5 when x = 8.
- x² at a negative x: Evaluate x² + 1 when x = −3.
- two letters, two values: Evaluate 3x − 2y when x = 2 and y = −3.
- powers and terms: Evaluate 2x² − 3x + 4 when x = −2.
- a group with a power: Evaluate 3(x − 1)² + 2 when x = 4.
- two letters, longer: Evaluate x² − 2xy + y when x = 3 and y = −2.
- a fraction bar: Evaluate (x + 6)/(x − 1) when x = 3.
