Swap a repeated phrase for a single compact mark you can write, scan, and rearrange fast. Unlike a name, which is still words, a symbol shrinks the concept to one glyph, so it must earn its learning curve by appearing often.

Example

In your chemistry notes, "the concentration of the reactant" becomes [A] and "the rate of the forward reaction" becomes k-sub-f. Two marks replace 11 words you were writing 30 times a page, so a rate law now fits on one line.
