The pseudocode for the program is given below:

import random

create class cal

                create constructor that takes two values set it to a and b respectively

                create function add that return a+b

                create function mul that return a*b

                create function div that return a/b

                create function sub that return a-b

function playQuiz

                print "0. Exit"

                print "1. Add"

                print "2. Subtraction"

                print "3. Multiplication"

                print "4. Division"

                take choice from user convert it to int

                generate random number between 0 to 9 and store into a

                generate random number between 0 to 9 and store into b

                create object of class cal

                continue until choice not equal to 0

  if choice is 1

then print "what do you think the sum of these two numbers are? a + b "

set number of tries to 0

while true

take input from user(sum of a+b) into sum

convert sum to int and store into answer

if answer is same as the value that is returned by calling the function add of the class cal

then print "Perfect, the answer is correct..."and return

else if answer is not same as the value that is returned by calling the function add of the class cal

then print "I am sorry, your answer is wrong kitto,Please Try again:"

and increment number of tries by 1

and check if number of tries is equal to 3

then print Max number of tries reached.

and ask user Do you want to try another question or quit? (T/Q):

if user enter T then return PlayQuiz function

otherwise do return only

                                if choice is equal to 2

                                                then print "what do you think the difference of these two numbers are? a-b"

                                                set number of tries to 0

                                                while true

take input from user( eg. 3 which is subtraction of a-b) and convert it to int and store into answer

                                                                if answer is same as the value that is returned by calling the function sub of the class cal

                                                                                then print "Perfect, the answer is correct..."and return
