Dec 16, 2018

tough especially since I have memory issue because of my disease (often forget halfway a sentence what I was trying to say, and in the beginning i couldnt read anymore, cause after the second word I had forgotten the first. Reading got like 60% better, still cant focus at all. but math .. I allways get stuck after the first number even with the most basic stuff like 18+5 it took me several minutes sometimes, cause my mind was like a record being stuck, couldnt get past 18+....18+.....18+..... )

so extremely happy I finished this one with 100% the first go !! And actually quite surprised!

100% isn't too hard if you know basic multiplication

Level 26

Nov 3, 2022

If you get a 2 digit number multiplied by a 1 digit number, here is a tip:

Example: 82 x 9

80 x 9 + 2 x 9

80 x 9 = 8 x 9 (72) x 10 = 720

2 x 9 = 18

720 + 18 = 738

82 x 9 = 738!

Let's see, I am still in my fathers womb blind, deaf, autistic, mentally challenged, with no fingers or toes. Also, neither of my parents attended to my birthing, my dad left me at the sad age of two. Also, I live in Ohio. Also, I can't even count more than 69. Also, my dad is Jeffery Dahmer. Also, my mother is Peppa Pig. Also, I have one brain cell.

And yet I got it done with 1:59 left. How does that make you feel.

Nov 15, 2025

People who say they do this in 50 seconds: you do realise that means 2,5 seconds a question? Personally for me that wouldn't be enough time to read the problem and type an answer, even if I knew it instantaneously. Let alone calculate it in my head. Do you calculate the answers prior to pressing 'Start', perchance?
