Solve the first equation for a in terms of b and c. Plug this value into the second equation to get a quadratic for b with coefficients in terms of c. Try and find solutions with b and c real by solving for the discriminant greater than zero. This gives you a quadratic in c that is always negative ...

While (obviously) I'd recommend getting a hold of another calculator, in the meantime you can replicate the modulo function.

How so? If you define "the preconditions for life" to be all conditions such that life will arise, then if those conditions exist life will arise. It's practically a tautology. I think we are defining preconditions for life as "conditions which would support life, should it arise"
