\*

Synopsis:

\*

A multiplication symbol that allows a line break. If there is a break then LaTeX puts a \times symbol, ×, before that break.

In \( A_1\* A_2\* A_3\* A_4 \), if there is no line break then LaTeX outputs it as though it were \( A_1 A_2 A_3 A_4 \). If a line break does happen, for example between the two middle ones, then LaTeX sets it like \( A_1 A_2 \times \), followed by the break, followed by \( A_3 A_4 \).
