This program simulates a

simple calculator, capable of performing

the seven

basic arithmetic operations using two integers. The user first selects which

operation they would like to do,

and then enters the two numbers to use.

The

options are add, subtract, multiply, divide, int divide, mod, and exponents.

The program then prints out the mathematical equation, along with the

answer. For example, if the user chooses subtract and then e

nters the

numbers 100 and 13, the program should print out

100

13 = 87

If the user selects an invalid choice of operation, they receive an error.
