Apparently there is an isomorphism between the additive group [itex](ℝ,+)[/itex] of real numbers and the multiplicative group [itex](ℝ_{>0},×)[/itex] of positive real numbers.
But I thought that the reals were uncountably infinite and so don't understand how you could define a bijection between them?!
Thanks for your help!
