The shorthand way to write a compound is by using chemical formulas or symbols. For example, water is written as H2O, where "H" represents hydrogen and "O" represents oxygen. Another compound, carbon dioxide, is written as CO2, where "C" represents carbon and "O" represents oxygen.
The chemists' shorthand for elements is called chemical symbols. For example, instead of writing out 'selenium,' it can be quickly written as 'Se.'
Anne Frank stopped writing in shorthand because it was difficult to keep up with writing in shorthand while hiding during the Holocaust. She needed to be quick and discreet in her writing to avoid detection, so she switched to regular handwriting to be more efficient.
He created Shorthand writing.
Scientific Notation helps scientists write big or small numbers in a shorthand way. For example, instead writing 5,230,000,000,000 it would just be easier to write 5.23 x 10 to the 14th power.

Speedwriting is the name often given to shorthand which uses the ordinary letters of the alphabet rather than symbols, for example Keyscript shorthand.

Shorthand
Symbols are used for elements, when writing chemical compounds. These clearly show reactions between molecules. This is chemical bookkeeping.
