A computing array based on a 1T1R device, an operation circuit, and an operating method. The computing array comprises: a 1T1R array and a peripheral circuit, wherein the 1T1R array is used for implementing an operation and storing an operation result, and the peripheral circuit is used for transmitting data and a control signal so as to control the operation and storage processes of the 1T1R array; the operation circuit is respectively used for implementing a one-bit full adder, a multi-bit ripple-carry adder and an optimized design thereof, a two-bit data selector, a multi-bit carry-select adder, and a multi-bit pre-calculation adder; and the operating method corresponding to the operation circuit respectively completes the corresponding operation and storage processes by means of controlling an initialized resistance state of the 1T1R device, a word line input signal, a bit line input signal and a source line input signal. The integration of computation and storage is realized, the complexity of the integr
