• Addition — is the mathematical process of putting things together. The plus sign + means that two numbers are added together. For example, in the picture on the right, there are 3 + 2 apples meaning three apples and two other apples which is the same as… …   Wikipedia

• Two's complement — The two s complement of a binary number is defined as the value obtained by subtracting the number from a large power of two (specifically, from 2 N for an N bit two s complement).A two s complement system or two s complement arithmetic is a… …   Wikipedia

• Modulo (jargon) — The word modulo (Latin, with respect to a modulus of ) is the Latin ablative of modulus which itself means a small measure. It was introduced into mathematics in the book Disquisitiones Arithmeticae by Carl Friedrich Gauss in 1801. Ever since,… …   Wikipedia

• Primitive root modulo n — In modular arithmetic, a branch of number theory, a primitive root modulo n is any number g with the property that any number coprime to n is congruent to a power of g (mod n ). That is, if g is a primitive root (mod n ) and gcd( a , n ) = 1,… …   Wikipedia

• Differential equations of addition — In cryptography, differential equations of addition (DEA) are one of the most basic equations related to differential cryptanalysis that mix additions over two different groups (e.g. addition modulo 232 and addition over GF(2)) and where input… …   Wikipedia
