The addition operator (+) adds two operands together:
x = 7 + 10y = x + 3z = x + y
The subtraction operator (-) will subtract the second operand from the first:
x = 8 - 3y = 10 - xz = x - y
The multiplication operator (*) will multiply the given operands:
x = 2 * 2y = x * 3z = x * y
The division operator (/) will ...
