Your statement assumes the educational system values consistency, which is a clearly false assumption.
- thaumasiotes 4y agoTextbooks aren't that bad. Here's what Pearson's Algebra 1 says when introducing the novel concept of the radical sign: > The radical symbol √ indicates a nonnegative square root, also called a principal square root. I quoted that one because it's available on libgen ( http://library.lol/main/BE522034F8D3680B248162CD2C35D455 http://library.lol/main/BE522034F8D3680B248162CD2C35D455 , page 16), but obviously every basic algebra textbook covers this. The symbol is never discussed -- or used -- in any other terms than that it uniquely refers to a positive (or zero) square root.
- BeetleB 4y agoYour evidence is consistent with my claims. Or rather: I never claimed there aren't textbooks that define it as the positive square root.
- thaumasiotes 4y agoAll textbooks define it that way. There is no other definition available for that symbol.
