Common mistakes

Misconceptions students bring to algebra

Specific errors to watch for when reviewing student work — pulled from classroom research and teacher reports.

1. 1

   Distributing only over the first term in parentheses.

   What to teach instead: The factor outside the parentheses multiplies every term inside.

   3(x + 4) = 3x + 12, not 3x + 4.

2. 2

   Confusing a negative sign with subtraction inside an expression.

   What to teach instead: A negative coefficient sticks with the variable when you move terms.

   In 5 − 2x, the −2 is the coefficient of x, not just a subtraction.

3. 3

   Thinking x² and 2x are the same.

   What to teach instead: x² = x · x; 2x = x + x. They're only equal when x = 0 or x = 2.

4. 4

   Cancelling terms from a sum like factors of a product.

   What to teach instead: You can only cancel factors that multiply the whole numerator and denominator, not addends.

   (x + 3)/3 ≠ x. You can't cancel the 3s because the numerator is a sum.

5. 5

   Forgetting to flip the inequality when multiplying or dividing by a negative.

   What to teach instead: Multiplying or dividing both sides of an inequality by a negative reverses the direction.

   −2x < 6 → x > −3 (not x < −3).

Key vocabulary

Algebra terms students should know

A short glossary of core vocabulary you can drop into any worksheet, quiz, or study guide.

Variable

A letter or symbol that stands for a number that can change or is unknown.

Coefficient

The number multiplied by a variable. In 4x, the coefficient is 4.

Constant

A fixed number with no variable attached.

Expression

A combination of numbers, variables, and operations without an equals sign.

Equation

A statement that two expressions are equal, with an equals sign.

Inequality

A comparison using <, >, ≤, or ≥ instead of an equals sign.

Solution

A value of the variable that makes an equation true.

Like terms

Terms that have the same variables raised to the same powers, so they can be combined.

Distributive property

a(b + c) = ab + ac. Lets you 'distribute' multiplication over addition.

Slope

The steepness of a line, computed as rise over run.
