//Create a simple program that stores the values of 2 variables,
//Then perfoms the following operations and store the results in
//at least one other variable:
//-Addition
//-Substration
//-Multiplication
//-Square
//-Cube
//-Modulo
// if the result of the addition operation is less than five, then tell the user the numbers are low
// if the result of the addition operation is greater than five, then tell the user the numbers are high
// if the result of the addition operation is five, then tell the user the numbers are good
//Wee need to use the control statements to solve some complex problem and direct the flow of execution
//of our program:
