Why do we have to have numbers and know them how come we cant just have letters?

Answer 1

The Romans didn't use digits, and biblical Hebrew doesn't have digits -- both used letters to represent counts. From these examples, we know that "numbers" aren't needed.

Counting, though, is a really basic human function. How many people are with me today? How many spears am I carrying? How many children should I keep track of? How many hyienas are nearby?

Once you have counts, you may want to start manipulating them. Between us, how many goats are in our herds? How many buffalo skins do we have in the tribe? How many days will it take to travel?

Brain studies have found specific neuron clusters that count. It's deeply wired into our wetware.

So, digits we can do without. Doing without some counting system -- and the arithmetic that follows -- may not be possible.

Answer 2

(1) Since "letters" are used for words and sentences,
it would be confusing to use the same "letters" to stand for number values also.

For example, if A=1 and D=4,
then "AD" could either mean "ad" or "14".

How could you tell what the letters stood for?

(2) If you mean making up a new set of symbols to stand for numbers -- such as replacing 1, 2, 3 with other characters not already used in the alphabet -- that would be the same as using the given symbols we already use. It would be wasteful and create errors to convert all the current documents, computer programs, clocks, keyboards, etc. in the world to a new system for no reason since the new symbols would function the same way as the old symbols currently used.

Right now, the current number system is used universally worldwide, so any changes would have to be agreed upon or else you would have to "convert" between different systems.

(3) The brain reads and processes "number symbols" differently from "letter symbols." That is why it can be harder to remember or recite a license plate number, for example, that has both letters and numbers mixed together, rather than all letters or all numbers which is easier. Language and math are processed differently in separate parts of the brain.

Again, if you started mixing the function of letters and numbers together, it would cause confusion, introduce more errors, and slow down processing time where it takes longer to read, record, or transmit information.

What?

...numbers are (for the most part) universal. English isn't.
