• Digit sum — In mathematics, the digit sum of a given integer is the sum of all its digits, (e.g.: the digit sum of 84001 is calculated as 8+4+0+0+1 = 13). Digit sums are most often computed using the decimal representation of the given number, but… …   Wikipedia

• Sum-product number — A sum product number is an integer that in a given base is equal to the sum of its digits times the product of its digits. Or, to put it algebraically, given an integer n that is l digits long in base b (with d x representing the x th digit), ifn …   Wikipedia

• Sum addressed decoder — In CPU design, a Sum Addressed Decoder or Sum Addressed Memory (SAM) Decoder is a method of reducing the latency of the CPU cache access. This is achieved by fusing the address generation sum operation with the decode operation in the cache… …   Wikipedia

• Sum-Of-The-Years' Digits — An accelerated method for calculating an asset s depreciation. This method takes the asset s expected life and adds together the digits for each year. So if the asset was expected to last for five years, the sum of the years’ digits would… …   Investment dictionary
