Symbol for all real numbers in math
Generally, we use the symbol “P” to represent an irrational number, since the set of real numbers is denoted by R and the set of rational numbers is denoted by Q. We can also represent irrational numbers using the set difference of the real minus rationals, in a way $\text{R} – \text{Q}$ or $\frac{R}{Q}$.all of the counting numbers (1, 2, 3, etc.) plus 0 Integers: (can be positive or negative) all of the whole numbers (1, 2, 3, etc.) plus all of their opposites (-1, -2, -3, etc.) and also 0 Rational numbers: any number that can be expressed as a fraction of two integers (like 92, -56/3, √25, or any other number with a repeating or terminating ...
