It's a common requirement for setting up a password or username. Means it has to have 6 letters (or more) or six numbers or six symbols( ?!/()&*_ things like that) Or three letters and three numbers. Or two letters and two symbols and two numbers. Or something along those lines.
Numerals, such as '1' or '2' are symbols for numbers. Numerals are combined to represent larger or more complex numbers ("2,224", "19.5", or "2/3"). These numbers are symbols for, and need to be read as, spelled-out words: "one", "two", "two thousand, two hundred and twenty-four", "nineteen point five", or "two thirds".
PLease be more specific.

Letters are used to represent numbers. Say we have a hidden or secret number, we have to put something in its place. So the easiest thing to use is letters, because the alphabet is a fundamental system used for English-speaking people. Anything else would make math far more complicated then it already is.
Because it is more simple to write one or two letters than a word and also these symbols are valid in all languages.

you don't you can activate them but all they show is symbols numbers and letters if they do anything more I wouldn't know how

Binary can only be 1 & 0. Decimal numbers have a dot in them. Binary numbers use only 2 symbols (0 and 1) to represent different numbers, while decimal numbers use 10 symbols (0 to 9) to represent different numbers. check the below link for more.
Numbers are often considered universal because they represent quantities and can be understood and interpreted across different languages and cultures. While the symbols used to represent numbers may vary between languages (e.g., Arabic numerals versus Roman numerals), the concept of counting and representing quantities with numbers is generally consistent. However, numerical systems can differ, such as base-10 (decimal) versus base-60 (sexagesimal), which can influence the way numbers are expressed and manipulated.
Letters and symbols are used in equations to represent quantities, sometimes known or unknown. For example the symbol π (pi) represents the constant 3.14… and is unchanging. X or Y in an equation represent unknown terms that may vary depending on the equation, and other variables in the equation. There are numerous examples of both symbols and letters used in mathematical equations, but almost always they are either referring to a known constant term that is more simply expressed as a symbol, or an unknown or general term yet to be concretely determined.
What is algebra in maths? It is a part of math that works on the basis of symbols and the rules for manipulating those symbols. The formulas of algebra are quite interesting and practice of these formulas makes your brain sharper. Algebra also uses in your daily activity like sports, cooking, technology, and much more. It is easy to learn but for many students, it is a nightmare. With Ziyyara’s live one-on-one classes, you can learn more about it from global expert tutors.

The most secure password is one that is lengthy and contains both capital and lowercase letters. It is also more secure if you include numbers or special characters.
Elements are give symbols consisting of letters, and these are related to the names of the elements (in some language at some date). There are 26 letters in many alphabets, but more than four times that number of elements. So it is necessary to use some mechanism to distinguish among elements with names that start with the same letter. Adding numbers is done to designate the number of atoms in a compound, the isotope, and so on. The best solutions is to use pairs of letters for most elements.
There are more algebraic symbols, but these are usually used in more advanced algebra courses. Some of them use letters from the Greek alphabet like Sigma and Delta.
