thanks man u saved my life! i am really struggling with my logic design subj but its also my fault for being late as i am always too lazy to get up early in the morning....DARN...thanks man!:D

@Supermanu15 you are welcome! but be aware that in different courses they might use different terms and notations than me. For example:

i say "A-negated" others might say "not A"

and instead of writing a bar above A, they might write -A or ¬A or A'

instead of AB or A*B they might write A∧B or A∪B

instead of A + B they might write A ∩ B.

It's looks like a mess, but as for engineers - they almost always use the same notation as me.

Anyway, good luck with your studies!

YES! Awesome! My teachers never were able to explain the 1+1=1 enigma to me. Thank you so much, that made a lot more sense!

Subbed, and watching all your vids on boolean algebra.

Also, thanks for the video response. ^^

[keleshevCOM]

@Blixish Thanks for your feedback! If you find some places that are not very clear - feel free to point it out - I will try to fix it.

btw, didn't expected that you have interest in Boolean algebra when posting the video response :-)

And thanks for subscribing!

Neat.

@oakkathebest In boolean algebra, + does not refer to sum. Instead, + signifies an OR statement, meaning that if A OR B is 1, the solution is 1

[oakkathebest]

I am confused. In Binary addition 1+1=10 in which sum=0 and carry=1. but here 1+1=1. So, sum=1 or 0? Could you explain? I may have wrong concept.

[nomchews]

I think of it as 0=off, 1=on then you if create the rule on>off all the other rules fall come out nicely.
