A little game with the goal to calculate simpel math equations fast.

• time
• numpy
• random

try:
    number = int(input("Write something: ",))
except ValueError as e:
    print("NaN")

• Make small random math calculations
• Run again
• Make different kind of questions
• Catch non integer answers
• Stop stupid users/testers
• Make more kind of questions
• Print to text file
• Run faster on 2nd try
• More/less time dependent on type of question: +,-,*,/
