The greater than sign and the less than sign are mathematical symbols used to compare the size relationship between two numbers.
The greater than sign is a ">" symbol, indicating that the number on the left is greater than the number on the right. For example, 3 > 1 means that 3 is greater than 1.
The less than sign is "
It should be noted that when the two numbers compared are equal, the greater than sign and the less than sign are not satisfied, and the equal sign, i.e. "=" sign, should be used, for example, 2 = 2, indicating that 2 equals 2.
The invention and use of mathematical symbols are later than numbers, but their number exceeds numbers. There are more than 200 mathematical symbols commonly used in modern mathematics, and each symbol has an interesting experience.
Development of mathematical symbols: For example, there are several plus signs, and the "+"sign is commonly used in modern mathematics. "+"comes from Lavin "et" (meaning "harmony"). /kloc-in the 6th century, Italian scientist Nicolo Tartaglia used the first letter of Italian word "plu" (meaning "add") to indicate addition, and the grass was "μ", which finally became "+". The number "-"evolved from the Latin word "minus", which was abbreviated as m at first, but later simplified to "-"because of its fast writing.
It is also said that wine merchants use "-"to indicate how much a barrel of wine costs. After the new wine is poured into the vat, a vertical line is added to the "-",which means that the original line is erased, thus becoming a "+"sign.
