WebJan 18, 2015 · Since all the elements here are nonzero real numbers with the usual addition and multiplication, we can simply solve for e in the usual manner. So e = 1/2 in G and this is the identity under this operation. We now use a similar operation to find the inverse for a given element x. x y = 2xy= 1/2 -----> y =1/4 x. WebApr 12, 2024 · A nonzero number is any number that is not equal to zero. This includes both positive and negative numbers as well as fractions and irrational numbers.
