一天傍晚,小猴与灰灰兔一起做数学作业。有两道题目是这样的:54×56 85×85灰灰兔抓起笔在纸上写着竖式一步一步地计算第一题,因为乘以的数太大,所以计算必须要小心加耐心。突然,小猴眨了一下眼睛笑着说:“有了,我知道这道题的答案了,等于3024。”“你别瞎说,我看你连笔都没有抓,怎么可能算出来呢?”灰灰兔瞪着眼睛对小猴说。过了一会儿,第一道题灰灰兔做出来了,答案果然和小猴的一样。灰灰兔怎么想也想不通。小猴调皮地说:“你看,这两位数乘以两位数,它们十位上的数
One evening, the monkey and Gray-eared Rabbit do math homework. There are two questions like this: 54 × 56 85 × 85 Gray Rabbit grabbed the pen on paper to write the first step by step calculation of the first question, because the number is multiplied by too much, so calculation must be careful patience. Suddenly, the monkey blinked his eyes and said with a smile: ”Yes, I know the answer to this question, equal to 3024. “ ”You do not talk nonsense, I see you even the pen did not grasp how could figure out ?? “Gray-eyed rabbit stared at the monkey said. After a while, the first problem gray rabbit made, the answer is really the same as the monkey. Gray rabbit how to think of it. Monkey naughtyly said: ”Look, these two digits multiplied by two digits, the number of their ten
