Week 7 had a lot about congruences. This is one of these
key concepts in this course,
and in general. I mean you'll find congruences are used in a lot of
spots now that you - well once you know what it is,
you'll start to see it in different areas,
not just in mathematic but in other areas of
your studies at university, and
you'll be able to use it - like once you understand it,
you'll be able to make connections and…
it'll help you in the long term. I don't even know what else to say.
Let me just leave it at that.
So again these bullets at the side, these are
basically number markers, so multiply it by 2 and roughly every
2 minutes is one of these bullets.
So this week, we have a couple more named theorems.
Again congruence are at the core of all of these.
I think the word “congruent” is in each of these theorems.
We have a couple of examples,
and then we talked, at the end of the week, we talked about linear congruences,
and I actually broke this video up into two parts.
So there is a second part on the integers modulo m
So if you're looking for that concept and don’t see it here,
check out the second video.
