You can use Python to solve Math problems!

Python Math Operators

Symbol

*
multiplication
/

//

**
power or exponent
%
remainder or modulus
()
parenthesis
Python follows the Order of Operations, just like you learned in Math class.

+ -
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. 1.
    Assign the variable bday to the month of your bday.
  2. 2.
    Multiply bday by 5.
  3. 3.
    Add 6 to bday.
  4. 4.
    Multiply bday by 4.
  5. 5.
    Add 9 to bday.
  6. 6.
    Multiply bday by 5.
  7. 7.
    Add the number number of the day of your bday.
  8. 8.
    Subtract 165 from bday.
  9. 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)
