addition
Quick Summary
Addition is a fundamental mathematical operation where numbers are combined to form a single sum. It is represented by the symbol '+', and follows the commutative law, meaning the order of the numbers does not change the result (e.g., a + b = b + a). Addition also adheres to the associative law, where the grouping of numbers does not affect the outcome (e.g., a + (b + c) = (a + b) + c). In chemistry, an addition reaction involves adding an atom or group of atoms to a molecule, typically unsaturated compounds like alkenes or alkynes.1234

vectorTwo vectors can be added or subtracted. For example, to add or subtract vectors v and w graphically (see the diagram), move each to the origin and complete the parallelogram formed by the two vectors; v + w is then one diagonal vector of the parallelogram, and v
