46Method of complements — Complement numbers on an adding machine c. 1910 In mathematics and computing, the method of complements is a technique used to subtract one number from another using only addition of positive numbers. This method was commonly used in mechanical… …
47Transformation matrix — In linear algebra, linear transformations can be represented by matrices. If T is a linear transformation mapping Rn to Rm and x is a column vector with n entries, then for some m×n matrix A, called the transformation matrix of T. There is an… …
