Matrix Multiplication - from MathWorld

Logarithms and Significant Figures - For any log, the number to the left of the decimal point is called the characteristic, and the number to the right of the decimal point is called the mantissa. The characteristic only locates the decimal point of the number, so it is usually not included when determining the number of significant figures. The mantissa has as many significant figures as the number whose log was found.

The Inverse Formula - Recall that the inverse of a square matrix A is the matrix A-1 such that AA-1 = A-1A = I. If such a matrix exists then it is unique, but it need not exist. A matrix which has an inverse is said to be invertible or non-singular.
