Question from Florence, a student:

What does g(m-1,2n)+n for m>0, n>=0.

I think it means for a specific m and n, such as m=5, n=2

g(m-1,2n)+n = g(5-1,2*2)+2
= g(4,4)+2
= g(6,6)

Is this correct, if not how do you deal with this type of equation?

Hi Florence,

You are correct that for m = 5 and n = 2

g(m-1,2n)+n = g(5-1,2*2)+2
= g(4,4)+2

But you can't go any further. For example if the function is defined by g(p, q) = 2p + q then

g(4,4)+2
= 2 × 4 + 4 + 2
=14

and

g(6,6) = 2 × 6 + 6 = 18
