Product
  Changing the order – commutative property of multiplication 交換位置相乘 - 乘法交換性質
  The product is the same even if the order of numbers changes. 兩個數交換位置相乘,所得的積是相同的。
  Grouping the numbers – associative property of multiplication 結合來相乘 - 乘法結合性質
  When doing multiplication of three numbers, it does not matter which two numbers you multiply first. The product is always the same. 三個數連乘,無論先計算前兩個數或後兩個數,它們的積都是相同的。
  When two of the numbers give a product ending in 0,you can multiply them first to make the whole calculation faster. 當三個數連乘時,如果其中兩個數的積是整十或整百的數時,可先計算這部分,使計算更快捷。
