Jomo said: I am just using the subtraction operation. We are experts in knowing how numbers there are if you start with the number 1 1, 2, 3, 4, ..., 50 are 50 numbers. 1,2,3, ..., 2027 are 2027 numbers. 1,2, ..., 1046 are 1046 numbers. Now if want to know, for example, how many numbers there are for 23, 24, 25, ..., 50 we do the following. We know that 1,2,3,4, ..., 22 ,23, 24, ...,50 has 50 numbers. But we only want to know how many numbers there are from 23 up to 50. That is, we do not want to include the numbers 1, 2, 3, ..., 22---which are 22 numbers. We just compute 50-22 = 28 and we know that 23, ..., 50 has 28 numbers Click to expand... Your logic makes sense, but why do we have two answers? Your answer is that we have 900,000 numbers while Plato answer is 472392 numbers. Someone of you gotta be wrong! What do you think Dan, we give the Trophy to Plato or Jomo?
