# Math

## Introduction

You can use Python to solve Math problems!

## Python Math Operators

 Symbol Operation + addition - subtraction * multiplication / division // integer division ** power or exponent % remainder or modulus () parenthesis

Python follows the Order of Operations, just like you learned in Math class.

 Order of Operations Precedence Symbols Parentheses () Exponent ** Multiplication, Division (from left to right) * / // Addition, Subtraction (from left to right) + -

When doing Math in Python, you must specify multiplication when you want multiplication. For example: 3(4 + 2) instead of 3 * (4 + 2) will result in an error.

## import math

Python has a number of builtin math methods.

``````import math

# square root
print(math.sqrt(2))

# pi
print(math.pi)``````

## Examples

Write Python code that does the following:

1. Assign the variable bday to the month of your bday.

2. Multiply bday by 5.

4. Multiply bday by 4.

6. Multiply bday by 5.

8. Subtract 165 from bday.

9. Print the value of bday.

``````# Example birthday of 1/1
bday = 1
bday = bday * 5
bday = bday + 6
bday = bday * 4
bday = bday + 9
bday = bday * 5
bday = bday + 1
bday = bday - 165
print(bday)``````
