[Calculus] has two major branches, differential calculus and integral calculus; the former concerns instantaneous rates of change, and the slopes of curves, while the latter concerns accumulation of quantities, and areas under or between curves.

8008UM.pdf (8008.classiccmp.org) The 8008 is a complete computer system central processor unit which may be interfaced with memories having capacities up to 16K bytes. The processor communicates over an 8-bit data and address bus and uses two leads for internal control and four leads for external control. The CPU contains an 8-bit parallel arithmetic unit, a dynamic RAM (seven 8-bit data registers and an 8x14 stack), and complete instruction decoding and control logic.

Calculus (Wikipedia) Calculus is the mathematical study of continuous change, in the same way that geometry is the study of shape, and algebra is the study of generalizations of arithmetic operations.
