I thought that Roman Numerals were pronounced like the letters making up the numeral rather than like the number. For one birthday (I think I was about 8 or 9) I got the game Mega Man IV and would keep referring to it as "Mega Man I.V" (pronounced just like the abbreviation for "intravenous") even though my parents corrected me. I'm not sure how long it took for me to say it right.
I thought the word "divvy" was slang for "divide." So, I would say "8 divvy 2" instead of "8 divided by 2." I'm sure my parents and teachers were confused!
When I was little I thought you could get arrested if you accidentally skipped a number while counting.
When I was 5, I thought a calendar was called a counter
I thought 100 was the highest number
For some reason, whenever I visualized myself being 6 years old, I visualized myself as an actual number 6! I believe I did this until I was around 8.
When I was a kid I believed that the number 11 was pronounced "onety-one"
You know how some people used to think, you say "blast-off" instead of 0 when counting backwards? Well, I used to say "beep" instead, because I learnt it from our microwave, which always beeped when the food was fully cooked.
I used to think that the number 8 was a boy and that 7 was a girl
I used to believe there were numbers called "onety" and 'twoty." I thought "twoty-nine" came before twenty.
Until I was about 3 or 4 years old, I thought that the largest number was 18, and that there could only be 18 of everything. The first time I heard any number past 18 was once when I heard my mom counting to 20 (We were probably having a conversation about numbers), and I asked what the number "nineteennwenty" looked like.
When I was younger, I believed that times tables in maths were kids sitting at tables staring at clocks!
When I was in kindergarten, every Wednesday I went to this place where I visited this man who built obstacle courses for me to do. He also liked to spray shaving cream on the mats so we could write words and draw pictures in the shaving cream. One day we decided to write and solve some simple math problems in the shaving cream, and the guy wrote out one problem that really puzzled me. My brain did not certainly record my response, but I wall all like "What the heck? The letter A is not a number!" This was the first variable I ever solved for in my entire life.
When I was young I didn't get the whole concept of numbers or value of money. I thought that when you went to a store, you just gave them some money, and they gave you some back. I was very confused one time when my mother didn't get any change back, and acted like this wasn't a problem at all.
I Thought i was pretty smart as a young kid and liked to show off to my parents. On one roadtrip i wanted to show my parents i could count to a million, so i started counting and i knew up to 100 or so, but i remember my parents (maybe sick of my squeaky-voiced counting and "are you listening to me? Muuuum? Daaaad?") distracted me with a book i could write all the numbers instead
When I was a kid I thought there was a biggest number. I asked my mom and dadd what was the biggest number but they said there was no biggest number since you could always just add another zero. They tried to explain this to me multiple times but I just couldn't wrap my mind around it!
i used to think that my adopted mom, who even at the time was quite old, was actually 10 years old. i thought this because i could only count up to ten at the time, so i thought 10 must be pretty old. i also thought that i would become a grown up when i became 10.
Before I went to Kindergarten and was learning to count, I always left out the number 8: 1, 2, 3, 4, 5, 6, 7, 9, 10. And my mum and dad would always say (so they would tell me, as I don't remember this): "What ever happened to poor old 8?" And I apparently would have no idea. And strange enough, 8 is my favorite number today!
When I was in Kindergarten I used to believe 100 was the biggest number.
When I was younger, I used to believe that you couldn't count backwards unless you said "Zero, Blast Off!" at the end.
