Excel's storage of numbers in binary format also affects its accuracy. [3] To illustrate, the lower figure tabulates the simple addition 1 + x − 1 for several values of x. All the values of x begin at the 15 th decimal, so Excel must take them into account. Before calculating the sum 1 + x, Excel first approximates x as a binary number
The following table lists many common symbols, together with their name, how they should be read out loud, and the related field of mathematics. Additionally, the subsequent columns contains an informal explanation, a short example, the Unicode location, the name for use in HTML documents, [1] and the LaTeX symbol.
In algebraic notation, widely used in mathematics, a multiplication symbol is usually omitted wherever it would not cause confusion: "a multiplied by b" can be written as ab or a b. [ 1 ] Other symbols can also be used to denote multiplication, often to reduce confusion between the multiplication sign × and the common variable x .
Sometimes, multiplication symbols are replaced with either a dot or center-dot, so that x × y is written as either x. y or x · y . Plain text , programming languages , and calculators also use a single asterisk to represent the multiplication symbol, [ 6 ] and it must be explicitly used; for example, 3 x is written as 3 * x .

In mathematics, a formula generally refers to an equation or inequality relating one mathematical expression to another, with the most important ones being mathematical theorems. For example, determining the volume of a sphere requires a significant amount of integral calculus or its geometrical analogue, the method of exhaustion . [ 3 ]
