Working step by step

In mathematics, you often have to show your work. This means that you write down the steps to derive the final answer.

Solving an equation step by step Figure: Solving an equation step by step.

You can see in the figure that every step is evaluated automatically. The symbols on the left show the result for each line. If a step is incorrect, the system can sometimes give feedback to help you find the error.

Note

You should only write mathematical expressions. The system cannot understand language.

Exercise 1: You can see the same exercise below. Try to solve the equation step by step, like in the figure above. Press enter to evaluate your input. You can use the arrow keys to copy the previous equation.
