## Explanation

Numerals in the math code use only dots two, three, five, and six. The dot configuration corresponds to the configuration of the literary numerals, but is placed in the lower two-thirds of the cell. The numeric indicator, dots three four five six, is generally placed to the left of a numeral.

In two digit numerals, the numeric indicator is only used once before the first digit of the numeral. Its influence affects all of the numerals that make up the number following it until certain symbols are encountered; these include a space, another mathematical character, such as a percent sign, or a braille indicator, such as the punctuation indicator.

When there are several numerals on the same line with spaces separating them, the numeric indicator must be placed before each numeral that follows a space. The influence of the numeric indicator is ended by a space.
