this simple multiplication is made easier by taking an indirect route to the answers that arent obvious. for example, I take 48 x 4 and see it as 50 x 4 (which i automatically know is 200) minus 2 x 4 (8) and get the answer 192 in two seconds. But if I multiply 4 by 40 and then 4 by 8 and add them together it takes 2 or 3 times as long.

Funny the range of difficulty you get, I do this quiz a few times to get my brain going; on average I get it finished with about 15 seconds left, but I just did it twice ending with just under a minute left over because I got some quite easy questions. But then yesterday I did it a few times where I ran out of time with 1 or 2 still unanswered.

16/20 on this try. I guess it depends a bit on how many easy ones you get too. The ones I didn't have time for were: 24x18, 14x23, 33x17 and 71x8. Yes, the last one of those would've been easy, but didnt spot it when doing others.

Also I am only 13 and in 8th grade. But currently I have higher Iq than the average adult. And typing speed helps too

The average adult in the western world has an IQ of around 100, so I wouldn't brag too much about that. ;)

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!
