“如果按照整除就应该是商为2余数是2” 这种说法是错误的,整除就表示余数为0
英文上整除用:divided evenly or divisible
考试中常用表示整除的概念如下:
y is divisible by x.
y divides by x.
y is a multiple of x.
x divides y.
x divides into y without remainder evenly.
表示除法:
when y is divided by integer x, the quotient is q and the remainer is r.
关于除尽,也可能是整除,当r为0时
