The positioning of the glyphs inside a quadrat is specified by two (2) basic operators:

- the superposition operator (
`:`

) - the juxtaposition operation (
`*`

)

Fundamentally, these 2 operators are all that are needed to combine multiple glyphs inside a quadrat. Here are a few examples:

More complex quadrats can be rendered by combining more glyphs
together. The operators to superimpose or juxtapose glyphs are analog to
mathematical operators. That is, they have an order of precedence
(juxaposition "`*`

" is always evaluated before
superposition ("`:`

").

As such, there is a way to override the default operator precedence by grouping glyphs with the use of parentheses. Consider the following quadrats:

A1:X1*X1 this will render as glyphA1overX1andX1juxaposed.X1andX1are first combined, thenA1is rendered above them. (A1:X1)*X1 Because of the parentheses, this will render as glyphA1overX1which are first combined. Then the secondX1juxaposed to the first 2 glyphs. The order of the positioning operations has been changed.

Just like mathematical expressions, there is no limit to the number of operators, operands and parentheses you can include in a quadrat description. However, practically, Egyptians usually did not combine too many glyphs within a quadrat, for obvious legibility and semantic reasons.
