Question

Write a program in python that lets a child practice their arithmetic skills.

The program should first ask for what kind of practice is desired: addition(1), subtraction(2), or multiplication (3).

Two random numbers will be generated (0 - 9), and the child will have to either add, subtract or multiply them.

If the child answers the question correctly, congratulate them, and ask them if they want to play the game again. If the child answers that they DO want to play the game, give them two different numbers to try.

If the child answers incorrectly, repeated the question with the exact two same numbers, until they get it right.

Sample Run:

Would you like to add(1), subtract (2) or multiply(3): 1

What is 2 + 2 equal to: 3

That is incorrect, what is 2 + 2 equal to: 4

Correct! Would you like to try again? (1 for Yes, 2 for No): 1

Would you like to add(1), subtract (2) or multiply(3): 1

What is 3 + 8 equal to: 3

That is incorrect, what is 3 + 8 equal to: 11

Correct! Would you like to try again? (1 for Yes, 2 for No): 2

Thank you for playing!

Python program :

import random
flag=True #declaring variable flag to break the loop when set to false
#using while loop
while flag:
    #asking user operation
    operation=int(input("Would you like to add(1), subtract (2) or multiply(3):"))
    #checking operation
    if operation==1:#when addition is choosen
        #generating two random numbers between 0 to 9
        num1=random.randint(0,9)
        num2=random.randint(0,9)
        ans=0 #declaring variable to store answer
        while ans!=(num1+num2):#using while loop
            ans=int(input("What is "+str(num1)+" + "+str(num2)+" equal to :"))
            if ans==(num1+num2):#if answer is correct then
                wantToContinue=int(input("Correct! Would you like to try again? (1 for Yes, 2 for No): "))
                #checking value of wantToContinue

        num1 = random.randint(0, 9)
        num2 = random.randint(0, 9)
        ans = 0  # declaring variable to store answer
