A character that is not a number or a letter. For example, the less than ( < ) is considered a symbol. The trademark, Copyright, end marks, and other special symbols not found on the keyboard are also considered to be symbols and must be inserted through the program.
How to insert the symbols next to numbers on a keyboard?
On the computer keyboard, the top row of number keys has one or more symbols above or next to the number. For example, on a U.S. keyboard, the $ (dollar sign) is above the number 4 key. To insert the dollar sign, press and hold down Shift, then press 4.
If the keyboard key has more than one symbol, hold the Alt, Ctrl, or Shift key, and then the number key to insert the third symbol. The keys vary depending on the operating system and language being used.
