Excel can solve equations through several of its mathematical functions, but the single Excel tool that works on the largest variety of equations is the program's Solver Add-in.

Computer scientists have devised an innovative and elegantly concise algorithm that can efficiently solve systems of linear equations that are critical to such important computer applications as ...

The new proof finds a quicker way of solving a large class of linear systems by sidestepping one of the main techniques typically used in the process. That technique, called matrix multiplication, ...
