My reaction exactly! I'm not great with math so expected this one to be tough for me, but instead I finished it surprisingly quickly. I probably made some lucky guesses. Excellent quiz in any case!

for the prime numbers i was going to put in 397, but i took 39 instead. 39 is not prime (13x3=39).

What does "One word numbers" mean?
+7
Level 68
Mar 30, 2022
Numbers when written out in English. So 12 is "twelve", 73 is "seventy three". This must be only one word.

SPOILER ALERT: Doesn't seem to accept a lot of "one word" numbers -- I tried each of one through twenty, thirty, forty, fifty, sixty, seventy, eighty, and ninety. Wouldn't accept any of those and I would assume that that is what is meant by "one word" answers. After trying the quiz, the statistics that show the percent of users who got each answer right display the correct response, but the quiz won't accept "eleven" in the first blue box.

why isnt "73" or "700" working for "whose first digit is 7" it doesn't make sense to me

They must satisfy all clues above them in that category.

73 is not even.

700 is not between 1 and 100.
