Random Math

I was telling the kids how fast computers are, and to demonstrate I wrote this Python program to do simple multiplication, division, addition, and subtraction.

from random import random as rand
from random import choice
def randmath():
	ops = {'+': 31, '-': 32, '*': 16, '/': 32}
	operator = choice([i for i in ops.keys()])
	scope = 1 << ops[operator]
	num1 = int(rand()*scope)
	num2 = int(rand()*scope)
	mathstring = "{} {} {}".format(num1, operator, num2)
	result = eval( mathstring )
	print(mathstring , "=", result)
	
while True: randmath()

Since that scrolls by so quickly, you may want to try this version, which pauses two seconds between calculations.

from random import random as rand
from random import choice
from time import sleep
def randmath():
	ops = {'+': 31, '-': 32, '*': 16, '/': 32}
	operator = choice([i for i in ops.keys()])
	scope = 1 << ops[operator]
	num1 = int(rand()*scope)
	num2 = int(rand()*scope)
	mathstring = "{} {} {}".format(num1, operator, num2)
	result = eval( mathstring )
	print(mathstring , "=", result)
	
while True:
        randmath()
        sleep(2)

To get them all nicely tiled like that, right-click on the taskbar and select “Show windows stacked”
