Long Equation Formatting

To Whom it may concern:

1. Hello everyone, i already know about the CTRL + Enter command but only breaks addition operator in the next line. How about negative, multiplication or division? Its been hard to explain to our customer about the limitation of this function as this is very helpful to them in terms of documentation. They're using Mathcad15 and Prime 2.

2. What is the maximum column/width a MathCAD matrix can handle? Can it handle more then 100?

Thank You,
