the way i mentally do it is first do 80-30=50, then add 3 more.

Love the last one. 7 [effectively 70] minus 3 [effectively 30] = 40 then 5 minus 9 = -4 then 40-4 = 36.

Awesome! Have they practiced negative number results for subtraction before this?

I like the last one, subtracting from left to right. But is it applicable to 3 digits or above?

I think as: 80 is 50 away from 30. Then another 2 away for 28 (52 total so far) and another 1 away for 81 (53 total).

We don't HAVE to rely on (or go straight to) "two negatives make a positive" when subtracting negatives. Here are two visuals I recommend when learning this concept.

Frank and I discovered we both have things the other needs. I want to work with him because he's done far more work on the algorithm. We want to eliminate the misconception that it can't sell because no one will buy it without the algorithm. NOT true. We'll buy it without the algorithm. We don't need them. We'll do it ourselves and make TikTok wonderful again.

Winnie Odinga: For the last 15 years, I have worked at his side, no matter the dispensation. We are similar in a lot of ways, but in a lot of ways, we were different. We used to challenge each other, we used to test each and push each other #CitizenExplainer

This new AIUC-1 "AI agent compliance standard" is a massive grift. Everyone involved is taking something for themselves. The "losers" here are the companies that might rely on this thinking it means something and the startups that will have to pay to get audited.

This is why The Inner Circle Trader students are so repulsive to other people on X. Trading hasn’t been easy for YOUR STUDENTS. You have some nerve calling other traders liars because it’s hard for YOU. You created the algorithm but when struggling to read, others cannot have it easy?
