The aggregate functions are used to evaluate mathematical calculation and return single values. It can be calculated from the columns in a table. Scalar functions return a single value based on the input value. 

Example -.

Aggregate – max(), count - Calculated with respect to numeric.

Scalar – UCASE(), NOW() – Calculated with respect to strings.
