I'm new to go, and having trouble with math/big. I'm creating lots of equations, but math/big uses all methods, no functions, so my code is looking hellish.

Like, I want to do this:

code:

(y**2 - x**3 - 7) % p

But I need big/Int. I'd like to do be able to use it like this:

code:

big.Mod(big.Sub( big.Sub( big.Exp(y,2,nil), big.Exp(x,3,nil)), 7), p)

But since big.Int uses methods, I'm creating code that looks like this:

code:

a := new(big.Int).Set(y)
b := new(big.Int).Set(x)
a.Exp(a, big.NewInt(2), nil)
b.Exp(b, big.NewInt(3), nil)
a.Sub(a, b)
a.Sub(a, big.NewInt(7))
a.Mod(a, p)

And that looks ugly to me.

Am I doing this right?

Thanks. I�ll play around with using a receiver like that, but maybe you�re right and I�ll stick with what I have.
