Mathematical Induction - Proving Divisibility by 4 (1 of 2: Test and assumption)

[Sir_Budginton]

I remember when I learned proof by induction. I hated it so much, and division was the worst. Now I can do it, but I still watch to see how he teaches my second least favourite topic. (Second only to vectors)

So you're telling me that in Australia kids are studying this at school, while here in Argentina I had to study this in my first year of university..

Eddie Woo you are the best. Keep going!!

The way we learned in school is that in this type of exercises the first term is for n=0, 5^0+3=1+3=4 which is divisible by 4.

Please do linear algebra. Youtube as a whole can benefit from you teaching that to students across the world.

"pronumeral" ... instead of "variable" ... never heard that before. Vocab + math class!

What I did after was multiply everything by 5 then subtract 12 from both sides and then can express RHS as multiple of 4 to show true for n = k + 1

Why not use N+, if we're only interested in positive whole numbers?

there is a lot of arabic fans . if u just put an arabic subtitles you will increaseor even double ur views and subs

[IlValentino]

"Zahl" means number, "zählen" means to count

[_inabox]

Do we have to also specify that k belongs to Z+ ?

[Sculman]

I am german and didnt know the Z means "Zahl" :O

[crabby]

You do it a bit different to what I was taught to do.
