Jane was seriously wondering what made her day unhappy and she finally discovered it was the strange answer she gave her little sister on the HCF and LCM calculation. "Anything you multiply by zero is always Zero". she yelled at her little sister. " but how many factors does 9 have?", the little girl cried out. Ehm.... just 3 and 9, Jane said while she was trying to do a snappy check in her head. but her headache was that, if i count forward, i skip with three spaces but if i count backwards with a difference of three spaces i have zero. she shook her head in disagreement. please help Jane out by letting her know if zero is a multiple of 9 or not as she is still in the troubling and disturbing hands of her little sister!
