Meraklısına, eHOW'dan alıntı:
There are exceptions to this rule. Multiplication and Division should be performed in the order that they are written from left to right. That is, if we have the following problems...
20 ÷ 10 x 5, Division is done First and Multiplication Second, so the Solution to this problem is,...20 ÷ 10 = 2. Then 2 x 5 = 10. Similarly, in the problem,
20 x 10 ÷ 5 ,Multiplication is done First and Division second, so the Solution to this problem is,... 20 x 10 = 200. Then, 200 ÷ 5 = 40.
As you read from left to right, if the Operation of Division comes before Multiplication, then Division is done first and Multiplication after. And if the Operation of Multiplication comes first, then Multiplication is done first and Division after.
