Sign (mathematics) The plus and minus symbols are used to show the sign of a number. In mathematics, the sign of a real number is its property of being either positive, negative, or 0 . In some contexts, it makes sense to consider a signed zero (such as floating-point representations of real numbers within computers).The symbols for Complex Numbers of the form a + b i where a, b ∈ R the symbol is C. There is no universal symbol for the purely imaginary numbers. Many would consider I or i R acceptable. I would. R = { a + 0 ∗ i } ⊊ C. (The real numbers are a proper subset of the complex numbers.) i R = { 0 + b ∗ i } ⊊ C.Each subset includes fractions, decimals, and irrational numbers according to their algebraic sign (+ or -).
