The underscore (<) και το άνω πρόσημο (>) are symbols used in mathematics, physics, or computer science to represent order relationships between numbers, quantities, or expressions. For example, we can write that 2 < 5 (2 είναι μικρότερο από 5) ή ότι x > y (x is greater than y).

But how to make these marks on a keyboard? There are different methods depending on the type of keyboard you’re using, your computer’s operating system, or the software you’re typing on. In this article, we’ll explain how to make the bottom and top plates on an AZERTY, QWERTY, or HP keyboard, as well as in your main word processing or code editing software.

How to make the down and up mark on an AZERTY keyboard?

The AZERTY keyboard is a keyboard whose keys are arranged according to the French alphabet. This is the most common type of keyboard in France, Belgium or Morocco.

On an AZERTY keyboard, there is no key dedicated to the down or up symbol. To write them, you need to use a key combination. Here are the different possibilities:

• Use the key next to W: < (μόνο) ή > (with shift key)
  
  
• Use Alt Gr + < to < ή Alt Gr + > for >
• Use the key combination Alt + 60 (on the numeric keypad) to < ή Alt + 62 (στο αριθμητικό πληκτρολόγιο) για >

How to make the smallest and largest symbol on a QWERTY keyboard?

A QWERTY keyboard is a keyboard whose keys are arranged according to the English alphabet. It is the most common type of keyboard in the world, especially in the United States, United Kingdom or Canada.

On a QWERTY keyboard, there is a key dedicated to the down and up symbols. It’s at the bottom left of the keyboard, next to Z. To write them, just press this key: < (μόνο) ή > (with the Shift key).

How to make the down and up symbol on an HP keyboard?

The HP keyboard is a keyboard designed by the Hewlett-Packard brand for laptop or desktop computers. It can be AZERTY or QWERTY depending on the country it is sold in.

On an HP keyboard, the method of writing the lower and upper characters depends on the type of keyboard you have. If you have an AZERTY keyboard, you can use the same key combinations as described above. If you have a QWERTY keyboard, you can use the key dedicated to the down and up symbols located at the bottom left of the keyboard.

How to make less and more connection in word processing or code editing software?

Word processing or code editing software are programs that allow you to write text or computer code. Among the most well-known, we can mention Microsoft Word, Notepad++, Sublime Text or Visual Studio Code.

In this software, you can use the same methods described above to make the min and max sign on your keyboard. However, there are other ways to enter these symbols:

• Use the Insert Symbol function in the Insert or Edit menu. You can then select the lower or upper symbol from a list of special characters.
• Use the Find and Replace function in the Edit or Find menu. You can then type the HTML code for the down or up symbol and replace it with the symbol itself. For example, type < for < ή > for >.
• Use the “Insert Equation” function on the “Insert” or “View” menu. You can then write a mathematical expression with the lower or upper sign. For example, type x < y for x < y.

conclusion

Now you know how to make the bottom and top plate on a keyboard, be it an AZERTY, QWERTY or HP keyboard. You also know how to insert these symbols into word processing or code editing software. These signs are useful for expressing order relationships between numbers, quantities, or expressions. They are often used in mathematics, physics or computer science. For example, to write a mathematical formula with exponents or subscripts, you can use the keyboard shortcut “ctrl + M” in some software such as Word or PowerPoint.
