## Math Operators

There are several math operators that can be used to perform calculations:
• Addition `+`
• Subtraction `-`
• Multiplication `*`
• Division `/`
• Exponent `**`
• Parentheses `()`
Python follows the rules of PEMDAS, meaning that parentheses, exponents, multiplication, division, addition, and subtraction are performed in that order, from left to right. Example of calculating the area of a trapezoid:
```# area of a trapezoid
base1 = 8
base2 = 10
height = 20
area = (base1 + base2) * height / 2
print(area)
# 180
```
The values of `base1` and `base2` are first added together to get 18 since they are in parentheses. That value of 18 is then multiplied by `height` and divided by 2, in order from left to right. The resulting value of 180 is then saved in the variable `area` and printed to the console.
