You use variables to stand for numbers in algebra
The capital 'R' that has two vertical lines instead of one like the alphabet letter stands for "all real numbers". If it is a lower case 'r' it would probably be a variable.
In algebra, the letter "R" typically stands for the set of all real numbers. This includes all rational numbers (like integers and fractions) and irrational numbers (such as the square root of 2 or π). The symbol R is often used in equations and functions to denote that the values are drawn from the continuum of real numbers.
