List of Mathematical Symbols. R = real numbers, Z = integers, N=natural numbers, Q = rational numbers, P = irrational. numbers. Ë= proper subset (not the whole thing) =subset. 9= there exists. 8= for every. 2= element of.
1 Q or â, denoting the set of all rational numbers (that is, the set of all proper and improper fractions): Q = { a / b: a, b â Z, b â  0}. 2  For example, 1/4 â Q and 11/6 â Q. 3  All integers are in this set since every integer a can be expressed as the fraction a /1 (Z â Q). 4  R or â, denoting the set of all real numbers.
