Mathematics as a language:
- Mathematics is itself a language with its own symbols, words and rules of syntax. It is based on a certain consistent set of assumptions and built up from there according to the rules of logic.
- The understanding and application of such logic, necessary for developing mathematical thought, depends upon the level of development of ordinary language.
- For example, only after developing the ability to use conjunctions such as 'and', 'but', 'therefore' and 'or', are the children ready for mathematically logical statements such as "Every square is a rectangle, but every rectangle is not a square."
