Math Tips & Tricks

Percentages represent parts per hundred. To calculate a percentage, divide the part by the whole and multiply by 100.

To find percentage change, subtract the old value from the new value, divide by the old value, and multiply by 100.

The average (mean) is calculated by adding all numbers together and dividing by the count of numbers.

These calculations are useful for discounts, tips, grades, statistics, and many everyday situations.
