Two permutation and combination problems
1 the first line, then subtract a, the first b, and finally add a, the first b.

A ranks first with A33=3! =6

There is A33=3 at the end of line B! =6

A first, b last, 2! =2

Then four! -6-6+2= 14

2 1440

First, there are four languages! =24

There are 5 spaces, 3 math spaces, A35=5*4*3=60.

Then * * * has 24*60= 1440.
