Numbers are very important in Python. Simple commands can quickly solve mathematical expressions and equations.

Adding, subtracting, multiplying, and dividing are written intuitively in Python. (Python follows the order of operations)

When converting a string into a number remember to convert it to an integer first.

When dealing with decimals use floats. If you don’t, your code will break.

### Helpful Commands

These commands are useful when dealing with numbers. Below, *number* represents any numerical variable:

**abs( number)**: Absolute value of number

**pow(10, 3)**: another possible exponential expression, 10 is the base and 3 is the exponent

**max(4, 10)**: returns the largest number

**min(4, 10)**: returns the smallest number

**round(4.6)**: rounds 4.6 to the nearest whole number

**round(3.1415, 3)**: Rounds 3.1415 to 3 decimal places. (Would return 3.142)
