The useful skill I learned in a math class from my primary school is the multiplication form. This form is made up of results of multiplications between all the numbers from 1 to 9. For example, 2 multiply eight equals 16 and 3 multiply 7 equals 21. It is usually presented in the shape of stairs, and knowing it enables us to get the resultsof multiplications quickly.
This form is a compulsory content for all the pupils around China in their primary education. From Laokaoya. From day one, I spent a great deal of time familiarizing, learning and practicing it so that I will not forget it for my whole life. It has become my instinct and I can still speak out these numbers without thinking.
It was a middle-aged female teacher who taught me this form. At that time, I was quite numb and a slow learner. Even if it was a very simple question, I could get the result wrong. However, the teacher would not criticise me, but patiently explain again and again and guide me through the computing process. Finally, I caught up with my clas*ates and masteredthis form.

It is very useful in life. When we are shopping, we often need to do some simple calculation so that the goods will not exceed our budget. from Laokaoya. Without a calculator at hand, I often resort to this multiplication form to get my numbers and it never goes wrong.
