When I was 4 I asked my mom what number came after 100. She said 10. Until 2nd grade, I would go "97, 98, 99, 100, 10, 11, 12.."

I believed as a kid that there were "Irish numerals" just like there were Roman numerals. And that the letters for the Irish numerals were S, H, N, and T. (instead of Roman numerals I, V, X, and L - those were the only ones I knew at the time - I learned C, D, and M later)

I used to believe the number 3 was pronounced 'free'. In Kindergarten when we had to say the numbers out loud, I was like "One, two, free, four..." and my teacher told me otherwise.

I add genders to numbers and letters. Here is the list:
1,2,3,5,7, and 8 are male.
4, 6, and 9 are female.

A, K, P, Q, R, V, W, X, and Y are female.
B, C, D, E, F, G, H, I, J, L, M, N, O, S, T, U, and Z are male.

When I was younger I thought a dozen meant the same thing as a lot and so when I was in first grade we were supposed to collect coins for some charity and I asked my uncle, he asked how many I wanted and I said a dozen, and that was when I learned a dozen equaled 12

I used to believe that every number had a personality, gender and relationship with other numbers. Each number had their own personality. Here are a few examples. 1 was a sweet innocent boy. 2 was a bossy older girl. 6 and 7 were lovers, 6 was 7's girlfriend, 7 was 6's boyfriend. 7 was protective over 6. 10 was a sweet and protective guy who was in a love triangle with 11 and 12. However, when 10 got together with 11, 12 ended up together with 15. So they all ended up happy. 10 and 11 were dating and 12 and 15 were dating. 11 was sweet and goofy and 12 was mature and serious. 15 was a sweet and devoted guy who was very romantic with his girlfriend 12. 10 was a very sweet guy as well who was a protective and sweet boyfriend who cared a lot about his girlfriend 11. 13 and 14 were lovers as well. 13 was 14's girlfriend and 14 was very protective over 13. 13 often got into difficult situations, and liked to party. 14, 13's boyfriend was smart and helped her out with issues. 16 and 17 were lovers as well. 17 was a sweet guy and was the boyfriend of his girlfriend, 16. 16 liked to hangout, and had both a mature side and a silly side. 3 and 4 had a close relationship, similar to the relationship of 1 and 2, but 1 was more innocent then 3 and 2 was mroe bossy then 4. 4 was kinder. Anyway, I won't get into too many more details, but every number had a life like this. I had a big imagination for a little kid.

As a child i once arrived at the conclusion that the area of a given circle would be equal to that of a square with a distance around it equal to the circumference of the circle. So the area of a given circle with a circumference C, would be (C/4)^2.

I stubbernly tried to defend this principle during math class. A countering example was quickly found...

I used to believe that a couple could mean two or three.

Anon

I used to belive that ten was the biggist number

I used to think that once meant 2, and twice meant 3.

When I was younger I use to believe that one plus one equalled a window

until i was about 10 i thought a dozen is about the highest possible number - when i learnt that it is only 12 i was dead disappointed, i nearly cried, it was such a big shock ;)

I thought a "couple"(as in, 'a couple of towels') meant 3 or 4. My kindergarten teacher asked me to get some paper towels from the bathroom once, I asked her how many, she said a couple, I said so, 3 or 4 right, she said no, a couple means 2.
looking back, i should've known. I mean, 2 ppl going out r a couple, so a couple would logically equal 2.
btw, i know this isnt funny or anything but i dont have anything else

Up into about the 3rd or 4th grade i thought the number three was pronounced "Free"

I used to think that if you wanted to count from 100 to 200, you counted "100, 101, 102..." and so on, until you got to 109. Then it was 200. That belief only lasted about a day or two.

I used to believe that the abbreviation for pounds was pronounced "labs", and that the abbreviation for ounces was pronounced "Oz" (like the Wizard of Oz)

When I was about three years old, my two older sisters wanted to be teachers when they grew up so naturally I became their test student for all the things they were gonna do when they grew up. They taught me my multiplication tables successfully up to two times ten. So at the age of three, I used to believe anything multiplied by zero equalled zero. And I was right. =)
