ABSTRACT:
Apparatus and method for performing a mathematical operation, e.g., addition on two signals composed of a string of n digits or bits in a number system having a predetermined base wherein A.sub.i and B.sub.i represents each digit in the respective strings and with i being the specific column or bit number from 0 to n. The mathematic operation is performed by first circuitry on the A.sub.i and B.sub.i digits without reference to the results of that operation of any other column or bit number. Substrings of the B string are compared by second circuitry to corresponding substrings of C string which for addition is the base minus one complement of the A string. Third circuitry are provided responsive to the first and second circuitry to produce a resultant output signal composed of at least n digits representing the results of the mathematic operation.
