![]() I ultimately want to find a way to, given a times table of any size, calculate whether a given number will appear, and how many times.Īlso, I'm pretty sure that for times tables 7x7 and below, more than half of the possible numbers are represented on the table, but for times tables above 7x7, less than half are represented. ![]() I'm also having trouble seeing the pattern (or patterns) in the numbers with four representatives. I'm having trouble accounting for why 16 and 36 have three representatives. 4 and 9 make sense to me, as they are squares within the basic range of the times table, so they are hit by themselves, their square root, and 1. The four with 3 are the remaining squares - 4, 9, 16, and 36. ![]() The 23 numbers with 2 instances are kind of the default I guess. This makes sense - squares don't fall into that 4x5 = 5x4 redundancy. The six numbers that have only 1 instance are all squares - those of 1, 5, 7, 8, 9, and 10. They all have either 1, 2, 3, or 4 instances. I feel like the number 42 should be calculable from the natural log of 100 and 10, or something, but I can't really figure it out.Īlso, I counted the frequency of all the numbers represented. ![]() I couldn't figure out a satisfying reason like that for 75, 84, 96 and 98. I had to wonder, why 42? I counted the 58 non-listed numbers - most of them are either primes >10 or multiples of those primes. There are 42 out of a possible 100 numbers represented.
