Question: Can the multipule of a number be -ve. Suppose if we say how many 2 digit multiple of 5 are there?
Do we include -25,-35,..also or only +ve multipule... etc ??
that's a real good question for which I have no answer. I have observed that the questions will be very clear without such ambiguity:
...how many multiples of 5 are there between.....
..If n is a 2-digit positive integer and is a multiple of 5....
May be some gurus can chime in here to help
