Cardify’s Mistake Detail screen showing an algebra question, the student’s work, and a step-by-step solution — A saved algebra question in Cardify for iPhone

See one math mistake from start to finish

A student gets an algebra quiz back and sees that their answer was marked wrong. Here’s what a useful review looks like.

On the quiz

Solve 3(x − 2) = 12.

3x − 2 = 12
x = 14/3

During corrections

The first mistake is distributing the 3 to only one term. One way to correct it is to divide both sides by 3 first.

x − 2 = 4
x = 6

At the next study session

Try the original problem with the solution covered. Once you find an answer, substitute it back into the original equation.

3(6 − 2) = 12
