Calculations

Do you know how to calculate numbers? I can calculate numbers very well. I learned how to calculate when I was very young. What is two plus two? The answer is four, of course. How about twenty three minus eleven, mm.., the answer is twelve. Addition and subtraction are so easy. Multiplication and division are more difficult. What is three times six? Three times six equals eighteen. How about thirty two divided by four? Thirty two divided by four equals eight. You see, calculations are not very difficult.
