Is it normal that the "is over of" method is so memorable to me?
I learned "is over of = percent over 100" in 6th grade and it's been the most memorable math method I have ever learned, even though it's not the most commonly used one for me. No one I know knows it though!! How is this?? I've used it to solve problems with people before and they acted like they never heard of this witchcraft!!
IIN?
