Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
The situation where the same symbol carries different mathematical meanings depending on the context it appears in.
'-' can mean subtraction, negative sign, or 'opposite of.' Context tells which.
Example 1
mediumList three different meanings of the symbol - in mathematics.
Example 2
hardWhat does f(x) mean in each context: (a) f(x) = x^2, (b) f(2) = 4, (c) 'the function f'?
Example 3
easyWhat does the symbol | mean in |x| vs in \{x \mid x > 0\}?
Example 4
mediumIn 2^3 and x^{-1}, the superscript means different things in context. Explain.
