- Drag chips into the work circle to represent the problem and click .
- Drag plus chips on top of negative chips or vice versa to cancel them out.

When you drag a plus chip onto a negative chip they will animate and disappear to represent cancelling each other out.

A message will indicate if your answer is correct.
