The ℚ symbol (double struck capital Q) is used in math to represent the set of rational numbers.
In math, the capital letter Q is commonly used to represent the set of rational numbers, though this is typically depicted as ℚ with a double-struck or blackboard bold font, rather than a regular Q.
The set of natural numbers symbol (ℕ) is used in math to represent the natural numbers: 1, 2, 3, ...
The set of integers is represented by the ℤ symbol.
The set of real numbers symbol is a Latin capital R presented in double-struck typeface.
The set of complex numbers is represented by the Latin capital letter C. The symbol is often presented with a double-struck font face just as with other number sets. The set of complex numbers extends the real numbers.
The set of rational numbers, denoted as ℚ, can be defined by the quotient of two numbers belonging to the set of integers, where the divisor is non-zero.
