# Lesson 3.0: Multiplication Cross and Dot

## Symbols

$×\phantom{\rule{.3em}{0ex}}\text{multiplication cross}$
⠐⠦

$\cdot \phantom{\rule{.3em}{0ex}}\text{multiplication dot}$
⠐⠲

## Explanation

The multiplication cross is a two-cell symbol formed by a dot five prefix and a root of dots two three six. The sign is used whenever the multiplication cross appears in print. As a general rule, no space is left before and after a sign of operation when the expression is written in horizontal format across a line.

Multiplication is also shown in print with the multiplication dot. The multiplication dot is formed with a dot five prefix and a dots two five six root. Since the multiplication dot is never used in spatial arrangements, it is only necessary to learn how to use it in horizontal mathematical expressions. The guidelines and rules for using this symbol are exactly the same as those for the multiplication cross.

The sign of operation terminates numeric mode. The numeric indicator is required before a numeral that follows the sign of operation.
