Study Strategies
## Why Check Your Work?
Double-checking helps catch simple mistakes and makes sure your answer makes
sense.
### How to Check
- Plug your answer back into the original problem to see if it works
- Ask yourself: does this answer make sense in real life?
- Look for units and make sure they match
Checking your
work builds confidence and helps you learn from errors.
Examples
- After solving for x, put your answer back in the equation to see if both sides match.
- Ask: if you bought 100 pizzas for $10, does that seem right? If not, check your math!
