One of the simplest mathematical expressions available is 2 + 2 = 4.

Although the concept is very simple to understand, you should use mathematical symbols when writing, a relatively recent historical invention.

At one time, mathematicians worked in a relatively complex way without the use of symbols. Unthinkable today.

Learn more about math signs, where they came from and why, in this section that is available every day.

As I mentioned in the introduction, math lessons were often done without symbols. You can understand how difficult this can be if you can imagine that your elementary school problems will be solved without using addition, subtraction, or equation.

In fact, it can be very difficult to do it now without the use of symbols.

The first people we met in mathematics were the ancient Babylonians and Sumerians. Through their cunning, they were able to perform relatively complex mathematical operations.

Their numerical system had a base -10 but, unlike ours, a -60. The concept suggests that in the past, two people merged into the Sumerians and one group had a basic-12 system and the other a base-5 system. Solve 60 variables using 5 x 12.

They were able to solve quadratic equations, knew about square and cube roots, and were well versed in Pythagorean Theory before Pythagoras.

But they missed out on a few things. They didn’t have zero, that’s what I said about zero in my show, and they really don’t have any metaphors to make equations.

It doesn’t look like algebra as we know it.

The Egyptians, Greeks, Romans, and Arabs were able to perform mathematical tasks without using mathematical symbols.

Algebra is actually named by Arab scholars and comes literally Al-Jaber This means reconnecting damaged parts.

Until then, Arabic scholars had studied mathematics to anyone in history, but they still did not use much figurative language.

The last great classic Arab mathematician since the beginning of the 15th century? Al-Hasan Ibn Al? al-Qalas? d?, used symbols, but they were only letters of the Arabic alphabet.

The symbols we know and use today were not invented until the 15th century.

The first use of the plus sign was in 1489 by German mathematician John Widman.

The plus sign represents only the short form of the Latin word “t” “And” to say “And”.

Widman was also the first person to use the minus sign. The sign of subtraction is sometimes believed to come from the edge of the numerator.

He clearly stated his new word in the medical text. is there “What? When this is reduced, + it is also good.” To be more German.

There have been previous attempts to create symbols that did the same thing, but failed. The Egyptians had a plus sign and it could be used to cut out a mirror image, but they never went beyond that. Egypt.

Not long after the beginning of the 17th century, there was a sign of duplication. This is really just the letter “x”.

“X” was first mentioned in 1618 in the book by Scottish mathematician John Napier. Amazing canon.

He explains in his book the use of this new symbol, “Reproduction [i.e. unknowns] It connects the two proposed sizes with the symbol ‘b’ or ወይም or normally without the symbol if the values ​​are indicated by one letter.

Technically, in print, the duplicate symbol is not really the letter x. It is a small character of the same shape.

There may be confusion when you use the standard keyboard with “x” as a duplicate symbol and as an “x” variable. Gotfred Libniz, one of Calculus’ associates, did not want to use “x” for this reason.

To that end, a dot is sometimes used as a symbol of multiplication. This is often very popular in Europe, and can be very confusing because a point is used for a different type of vector multiplication.

When computers arrived, the star symbol * was modified just because it was in the ASCII character set.

Like multiplication, there are many signs of division.

The modern division symbols we use are called Early Owls. This is a straight line with points above and below.

This was first used in 1659 by Swiss mathematician Johann Rahman.

Of all the signs I have mentioned, this has been omitted by the modern mathematician. In fact, they can’t be used very well except for elementary school math lessons and some calculators.

I personally hate the statue. I find it really confusing and I don’t think children should be taught to use division because they will never see it again in their lives.

The preferred distribution signal is called solid or forward reduction. This is very similar to the horizontal line used in partitions, and conveys the same meaning. This was done much later and did not represent division until 1845.

The development of computer adoption was not available on most keyboards, so it only reinforced the use of the corporate body.

Equal sign has a very interesting background story.

Equal symbol was first used in 1557 by the Welsh mathematician Robert Record. Whitel rib.

He was writing equations in his book, and he had to write the phrase “equal” more than 200 times. He basically got sick of writing over and over again, so he finally made a mark so he didn’t have to write anymore.

In the book he says: And to avoid the dull repetition of these words, I set up a pair of parallels or duplicate lines, as I often use at work. [the same] Length, like this: = because two things cannot be more equal. ”

Three parallel lines There is a similar, less-used symbol simply called a triple bar. It was first used in 1801 by Carr Frederick Gauss, and is sometimes used in logic or modular mathematics.

The percentage mark is derived from the Italian phrase. It is abbreviated as “page” with two zeros, and in the end, “P” was removed and there was only a straight line with two zeros.

Is the square root symbol mentioned in the above al-Qalas? M?, Or possibly from the lower case letter “r”.

In 1525 the first use seemed like a confirmation sign. At the top of the horizontal line is called a vincalem, and in 1637 the René Descartes was added to the Czech sign to create the modern symbol we use today.

The Greatest and Lesser of the Symbols Created in 1631 by Thomas Harriot of England Analyzed arts to solve algebraic equations.

The infinite sign, the number 8 on the side, is even greater than the modern number 8 on the Hindu-Arabic number. The earliest evidence of this can be traced back to the 7th or 8th century cross of St. Boniface.

It was first used to describe the size. It was not until 1655. The English priest John Wallis used it in his book The conical parts. No explanation has been given as to why he was chosen, but one hypothesis is that the symbol used for the Roman numeral 1000 is the difference, which was the letter C, one I and then back c

The last sign I pass is Pi.

P is, of course, the only Greek letter. However, its use to represent the diameter of a circle to its diameter is actually relatively recent.

It goes back to ancient China and Egypt, where the ratio of the circle was unique to the diameter of the circle.

He began using the Greek letters Delta and Pie, which we call P. P was chosen because the word “perimeter” was the first letter, and Delta was the first letter “diameter”. In 1647, the Englishman William Owredd first used the pi on the Delta.

The first use of the alphabet to represent the ratio was invented in 1706 by the Welsh mathematician William Jones.

There is a lot to be said about Pie, but I have put that in a series, perhaps for next year’s P Day.

You may have noticed that most of these signs, especially the major ones, have been in use since the late 15th century and have been in use for over 100 years. Basically, after people started using symbols, it made math easier, and since then, many people have started accepting them for more.

Mathematical symbols are still being created today because new branches of mathematics create new ideas that need to be easily explained.

The mathematical concepts you think of it are not really different from the emojis. There is only one way to transfer complex thinking to a single character.
