Now add (when adding a negative and a positive, subtract the two numbers. Then keep the symbol of the greatest number for the result. Since 20.25 is greater, the result will be positive):
![-10+20.25=10.25](https://img.qammunity.org/2021/formulas/mathematics/high-school/wasmc9gafnlvbloxsqw9pgb3jkxrugfnfc.png)
