Adding two whole numbers always gives you a whole number.
Multiplying (which is similar to addition) always gives you a whole number.
Subtracting does not always give you a whole number (Example : 4-10=-6, which is not a whole number).
Dividing two whole numbers does not always give you a whole number (Example: 2/3 is not a whole number).
