List of mathematical symbols. The list below has some of the most common symbols in mathematics. However, these symbols can have other meanings in different contexts other than math. If x=y, x and y represent the same value or thing. If x≈y, x and y are almost equal. If x≠y, x and y do not represent the same value or thing.

Here the minus signs are understood as labels to be used as part of the symbol, e.g. “-3”. 3. As a “Flip” Operation. Soon after we learn about negative numbers, we would learn about the third meaning of the minus sign – the “flip” over zero. For a positive quantity or expression, the minus sign flips it across zero on the number line.
