"5 times 4 is … uhhhhh….20." The deeper into math that you get, the harder the easier things become sometimes. XDDD
-
Mathematician small talk: “So what numbers are you into these days?”
-
As a programmer, what gets me is that he went back and modified his code, but didn't remove the redundant print statement.
-
I love how Matt is willing to think and even make mistakes on camera. That kind of security in one’s intelligence probably makes someone really easy to get along with.
-
The base 2 version of this game is pretty sad
-
lot of people saying 327 isn't prime, I think he means the individual digits are prime
-
Matt: writes code Matt: "That can't go wrong." Me: waits to see how that'll go wrong
-
I love how “Suggested: The Parker Square” pops up in the corner when Matt says, “I’m always one to give it a go.”
-
uses calculator "2 × 7.... equals 14" Literally me when I write an exam. Can't go wrong lol
-
At first I thought that Matt was extremely brave to be so confident in his coding skills that he would be willing to do it live on the internet in front of an audience of nerds. Then I realized that Matt is not ashamed to be caught making mistakes. In truth, that's one of the things I admire most about him.
-
For some reason, I always like videos about really big numbers. It seems it’s more interesting for a large number to be special.. because it’s so specific!
-
I think Matt hit on an important bit when he mentioned the base-ten-ness of this problem. Consider that in base 2, you can never have a number that multiples to anything other than 1 or 0. Has anybody checked for patterns across bases?
-
"i'm always one to give it a go" parker square shows up in the i-card
-
I paused this at 3:40 and thought "I could code this!" So I did. Then I came to the video...and watched him decided to code it.
-
12:52 "I'm always one to give it a go" (i) symbol recommends The Parker Square savage
-
I loved watching him code along with showing the math problem. Please do this more often!
-
12:53 Matt be like "I'm always one to give it a go" Top right corner suggestion: Parker Square
-
9:40 - u have nice hairstyle on your shadow)))
-
I love that thumbnail. The way he looks, with such fascination, at the number 277777788888899 as if it's the most attractive thing in the world 🤣🤣🤣
