originally it was decided to display numbers using the concept similar
to that used with braille. A special numeral sign () was used followed
by the letters A to J, which stood for the digit. For example, C is for

familiar with it.
However, it was then thought this traditional way of displaying
numbers could be too difficult for some new Moon readers, particularly
those who may have additional learning difficulties. StaffsMaths was
developed which uses a different set of symbols for numbers, as
The font for this set of numbers is sometimes referred to as the
Wibble font. It can be downloaded here (see Downloadable Moon Font).
Some embossers do not have the facility to produce StaffsMaths
numbers because of the complexity of the design. In these instances the
numbers can be produced using heat fusers or the sticky number tiles
which are available from the RNIB.
