Well, there are simple symbols, such as

a + b

,

a - b

,

a \times b

,

a \div b

But, there are also other symbols
For example, there is a symbol for difference used in some equations

△ y

. For instance

\frac{△ x}{△ y}

is the same as

\frac{x_{2} - x_{1}}{y_{2} - x_{1}}

There is also a symbol for sum

\sum_{n = 0}^{10} n

This is the symbol for summing a function of n denoted as a capital sigma. The bottom number denoted as n is the starting number. The top number is the ending number. You then plug in n for each number up to 10 and add them up.

\prod_{n = 1}^{10} n

is the symbol for product denoted as a capital pi. In this case, you have the same rules for summing apply to products, but you multiply instead of add.
