25 pennies is one quarter
The difference of p and q can be written : p - q Twice the difference is therefore 2 x (p - q) which can also be written as 2(p - q) OR 2p - 2q. Consequently you can create another variable (say) y and make this equal to twice the difference of p and q by simply writing, y = 2(p -q)
P! / q!(p-q)!
If B is between P and Q, then: P<B<Q
4(p + q), or 4p + 4q
