ZeroWidthTimes

This function has not been fully integrated into the long-term Mathematica system, and is subject to change.

ZeroWidthTimes
is an option for selections that specifies whether blank spaces representing multiplication are explicitly shown.

In Mathematica, a blank space between two symbols represents a multiplication sign. By setting ZeroWidthTimes->True, you can make such a blank space invisible while retaining its meaning as a multiplication symbol. This is useful for simulating conventional mathematical notation, such as ab + ac + ad = a(b + c + d).

With the default setting ZeroWidthTimes->False, a blank space between two objects being multiplied is explicitly shown, as in a b + a c + a d = a (b + c + d).
