Parallel (operator)

The parallel operator $\|$ (pronounced "parallel",^[1] following the parallel lines notation from geometry;^[2]^[3] also known as reduced sum, parallel sum or parallel addition) is a mathematical function which is used as a shorthand in electrical engineering,^[4]^[5]^[6]^{[nb 1]} but is also used in kinetics, fluid mechanics and financial mathematics.^[7]^[8] The name parallel comes from the use of the operator computing the combined resistance of resistors in parallel.
