The chemical symbol for nitrogen is N and it used so that compounds can be given a chemical formula such as NH3 and can be represented in chemical equations for the ease of identifying what elements are in what compounds.
THE PLUS SIGN (+)an example is: sodium + oxygen --> sodium oxideNa2 + O --> Na2O

It is more simple and practical.

So it is wrong equation .Symbols are very important
The chemical symbol of silver is Ag: chemical symbols are used in chemical formulae and equations.

Each chemical element has a different chemical symbol formed from one or two letters: H for hydrogen, U for uranium, Cl for chlorine, Ar for argon, etc. Symbols are used for simplicity in writing equations, etc. The chemical symbol can be considered as a code.

Delta as a mathematical symbol usually means "change". It's usually used the same way in physics and chemistry, though it's sometimes used in chemical equations to represent heat.

In Microsoft Word, chemical equations can be entered using special character menus. For example, subscripts and superscripts can be used to denote isotopes, and arrows can indicate reactions.
Because they are shorter.
