Gyaltsan,a Tibetan man from Nyingchi city in the Tibet autonomous region has created a new type of multiplication chart(乘法表)that helps primary school students calculate(計(jì)算)faster.

　　Different from the small and big 9×9multiplication charts,which are used nationally and make use of numbers the new chart uses 31Chinese characters, including 11 referring to numbers.

　　Gyaltsan showed a talent for math at school, but he left before finishing primary school.Four years ago. according to the 9×9multiplication charts.he began to create a new chart based on formulas(公式)coming from Tibetan chess and dice games. Through repeated experiments with his daughters,the new system finally worked.

　　The chart is better suited to primary students between grades three and five,but anyone can learn and it is very helpful to oral arithmetic(口算）skills.Even slower students take less than 8minutes to finish 120 multiplication exercises, while it takes one of the best fifth grade students at Lhasa's Second Primary School up to 16minutes to finish the same number of exercises without using his method.

　　Legdron, Gyaltsan's youngest daughter, who is a fifth grader, is a direct beneficiary of her father's invention.She said that she studied the chart during her winter vacation last year, and it took her about a month to learn it by heart.

　　“When we do multiplication,I am much faster than students who have not learned it,and I find it so convenient,"the 11-year-old said. "My math used to be poor,but since I mastered the chart, I've progressed, and my grades are now in the upper-middle rank in class.”
