The ancient Egyptians had ways for writing plurals. These are plural values that don't represent specific quantities.
The hieroglyph for 1 is the ideogram symbol, meaning that the character it follows is meant to be read literally. It is a way of saying 'one of these'. A single instance of this hieroglyph acts as an the ideogram symbol, but adding more than one of these characters implies a plural value.
Adding the hieroglyph for 1 is like saying ‘one of these’….
Just like the modern words ‘several’ or ‘many’, the Egyptians had ways of writing non-specific numbers.
Adding two 1 hieroglyphs is like saying ‘several of these’….
Adding three 1 hieroglyphs is like saying ‘many of these’…
