In the lattice above, what is the length of the shortest path of B→A ...?

What is the total number of different routes?

In the lattice above, what is the length of the shortest path of B→A ...?

What is the total number of different routes?

What is the length of the shortest path of B→A ...?

And what is the total number of different routes?

Now! Now! Look...!!ㅋ.F!!~~

So now, ........................................~~^^!!

Near the point B...

...another very very much nearby point A is approaching to B...~~^^!!

The path does not deviate beyond the triangle ABC

Not longer than (a+b)...I mean...It doesn't go round any further than that.

Let's assume that n of those different random paths are chosen randomly.

(Whether it's a straight line, a curved line, or a broken path, ...) 

Let the length of each path be ldn.

At this point, (the lowercase letters of L, ) l and d, 

Do write the two letters as close as possible. 

However, you must be able to distinguish between the two letters.....

......!!ㅋ..ㅋㅋㅋㅋㅋ._.F!!~~

If then,

What should we name the expression below~~~!!^.^????
