Title: Math riddle my 8th grader needs help with? Post by: MicroGuy on August 17, 2016, 02:30:00 AM My son was asked to use the number 4 in a math problem 16 times so that the result equals 5000.
So far the closest we've gotten is 5004. The problem can only contains 4's. Title: Re: Math riddle my 8th grader needs help with?
