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.

3. Add 6 to bday.

4. Multiply bday by 4.

5. Add 9 to bday.

6. Multiply bday by 5.

7. Add the number number of the day of your bday.

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)
