You use variables to stand for numbers in algebra
Algebra.
The point of using letters in algebra is that they can stand for any number (or a range of numbers that are, as yet, unspecified). There is no specific letter allocated to a number.
The algebra section of the DAT is used to evaluate your ability to use numbers and show that you're capable of prblem solving.
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.
That is called "algebra".That is called "algebra".That is called "algebra".That is called "algebra".

Unless you are restricted to a field or range using only nonnegative numbers, yes, you can use them.
The algebra taught in high school involves doing calculations with unknown or unspecified numbers. These are usually represented with letters, which are called "variables". For more details, read some introductory article about algebra, such as the Wikipedia (article "Elementary algebra"), or read a high school textbook about algebra if you want more details.
The letters in algebra stand for unknown numbers or amounts that you are trying to find out (calculate).For instance you have 3 things and you want to find out how many you have to add to get 5 things. You call the unknown amount X (or any letter you like) and you use an algebra equation to find the answer. So:3 + X (the unknown) = 5...and you already know the answer is 2, but when you learn the rules of calculating with algebra, you will be able to find the answers to much more complicated mathematical questions. Basically, you call the unknowns any letter you want, then you make an equation using the numbers you do know, and then you solve the equation.
Yes, numbers.

It is algebra that uses letters to represent numbers and also Roman numerals.

all kinds of things are different like the way we use more numbers and have technology to help us
