When my kids were in school, they like all the other kids, had to learn their numbers. So each day for homework, they would bring home a list of numbers on a piece of paper, and they were asked to write out the letters that spelled that number, right next to each of them. So the number seven would be there, there’d be a blank space, the kids would have to write S – E – V – E – N. And of course they were also asked which numbers were spelled out by the various combinations of letters, so they’d see S – I – X – T – Y and write 60, etc.
One day, my son presented me with a list of numbers and he said, “These numbers are different. There’s something special about them.” Here are the numbers:
Four, Six, Twelve, Thirty, Thirty Three, Thirty Six, Forty, Forty Five, Fifty, Fifty Four, Fifty Six, Sixty, Seventy, Eighty One, Eighty Eight, Ninety, and a Hundred.
What is special about this list of numbers?

You can divide the odd numbers by 4 and the even numbers by 6
No, that’s not it. Keep trying.
You can divide the number by how many letters it have and get a whole number 100/10 = 10 , 4/4 = 1, 6/3=2
Still way off. Keep trying!
each number is a multiple of the number of letters in it.
four 4 = 4 x 1, six 6 = 3 x 2, twelve 12 = 6 x 2, thirty 30 = 6 x 5, thirty three 33 = 11 x 3, thirty six 36 = 9 x 4, forty, 40 = 5 x 8, forty five, 45 = 9 x 5, fifty 50 = 5 x 10, fifty four, 54 = 9 x 6, fifty six 56 = 8 x 7, sixty 60 = 5 x 12, seventy 70 = 7 x 10, eighty one 81 = 9 x 9, eighty eight 88 = 11 x 8, ninety 90 = 6 x 15, one hundred 100 = 10 x 10,
