判断一个数能否被另一个数整除,不仅可以用割减法,也可以用割加法。割加法的依据是:如果一个加数与和都能被某数整除,则另一个加数也能被某数整除。根据这一规律,只要割去被判断数的末位数,再加上割去数的几倍,连续割加下去,如果最后得到的和是某数的倍数,那么这个数就能被某数整除。割加法主要用于判断一个数能不能被另
To determine whether a number can be divisible by another number, not only can cut law, you can also use cut law. The cut-and-add method is based on the fact that if one addend and sum both are divisible by a certain number, the other addend can also be divisible by a certain number. According to this law, as long as the last number of cut off the number of judgments, coupled with the cut several times the number of continuous cut plus, if the sum of the final and is a multiple of the number, then the number can be a certain number Divide Cut addition is mainly used to determine whether a number can be another
