When students make a common mistake in answering a question in our *Principles of Microeconomics* software, the program’s artificial intelligence **pinpoints their exact error and provides detailed feedback to correct the mistake. **

The software not only tells students what they got wrong, but *why *they’re wrong—letting students immediately fix their errors before committing them to memory.

This feedback is provided through the tool **Explain Error**. View examples of it below!

## Example from Chapter 3: Demand and Supply

In the following question, we ask students to calculate the change in quantity demanded of apples. To solve for this, students will need to know the formula for cross price elasticity of demand.

**Explain Error** will provide this formula, and in this scenario we also identify that the student made a simple math error when solving for the quantity demanded of apples by dividing the cross-price elasticity (given) by the % change in price of oranges (given), rather than multiplying those two values.

## Examples from Chapter 5: Elasticity

We provide specific feedback to help students who are struggling to apply the concept of elasticity to labor supply by explaining how a change in wages will or will not impact the job mentioned in the question.
