Okay, so in this problem, we have this table where we have x and y, x and y, and we have first 11 and 34, and then we have 12 and 33, and then we have 13 and 32.
00:20
And then finally we have, what was the last one? oh, i should know, 14 and 31.
00:24
I need to scroll down just a little bit, 14 and 31.
00:28
Okay, so notice what we have here, as this goes up by one, this goes down by one, right? we're going from a little bit.
00:34
11 to 12, or then we're going from 34 to 33.
00:37
So the total is always going to be the same, right? if i wrote a total right here on the right side, it would be 45, right? and then again, 45.
00:45
It'd be 45 all the way down.
00:47
So that means that they always add up to 35...
