所谓算式谜是指一类用字母或者文字代替数字的趣味数学题,据说起源于中国和印度。这些含有未知数字看上去残缺不全的算式,就像“谜”一样令人琢磨和费解,同时也会激发数学爱好者的兴趣。算式谜一般可以分为三类:一是纯粹的字母算式谜,算式中不同的字母代表不同的数字。在字母算式谜中,还有一种双重满足算式谜,也就是字母表达的数的原来意义也满足算式,例如算式谜THREE+THREE+ONE=SEVEN,字面含义是3+3+1=7,数据答案是23677+23677+517=47871;二是虫食算(形象地表述算式中一些原有的数字被蛀虫啃掉,需要推算还原),算式中给出了个别数字、其余
The so-called mathematical puzzle refers to a class of letters or words to replace the number of interesting mathematical problems, is said to originate in China and India. These formulas, which look like incomplete numbers with unknown numbers, are just as pondering and convoluted as the “mystery”, and they also stimulate the interest of math enthusiasts. Computational puzzle can be divided into three categories: First, the purely alphabetical formula puzzle, different letters in the formula represent different numbers. In the alphanumeric puzzle, there is also a double satisfy the puzzle, that is, the original meaning of the number of letters also satisfy the formula, such as the formula puzzle THREE + THREE + ONE = SEVEN, the literal meaning is 3 + 3 +1 = 7, the data The answer is 23677 +23677 +517 = 47871; the second is insecticide food (vivid expression of some of the original figures are chewed away by insects, the need to calculate the reduction), the formula gives the individual figures, the rest
