The board of education must commend this guy for definitely teaching a next generation of stem majors. He has helped me in every stem class since 11th grade and I am in year 3 of college.

I'm from Bangladesh and learning this for my admission exam. Thanks Thanks. You didn’t take a lot of time. I really like that. 😊 Keep it simple and easy, no need to exaggerate.

[@Alex-us1zp]

I just wanna say I am currently in a CS50 virtual course and 30 mins in it started to not make sense because I have no prior knowledge of binaries. So, I skimmed on how to convert binaries and discovered hexadecimal. But in order to properly know why it is important I need to know operations on binary, and it led me back here. I was here back in 12th grade and I never knew self-learning how to code is gonna lead me back here. Thank you!!!

[@webmaster246]

In terms of subtraction as the first subtraction example given. I see a tricky part that also not mentioned in detail however I tend to assume the author teach us with all love spared. What is missing in this example, it's not mentioned that we use 10-base as by pass (workaround) which after conversion to 10 base made gives us 2-1 respectively (as a result we get) = 1, which re-converted to 2 base is 01 or just 1. I mean as mentioned in the previous comment this guy does his best teaching us and I am appreciated for all his time spared, but you cannot learn science without questioning people you been surrounded by. It means that always ask even if looks nice to you. It means that no one is perfect besides the fact they can explain it pretty well. TL;DR for subtraction : always have online converter otherwise binary cheat sheet (conversion table) at hand (or learnt by heart, what a burden!) convert each row in the stack of subtraction process to 10-base, do the arithmetics, re-convert to 2-base for output as final 2-base solution. This way of thinking works best for me. Cheers.
