An equation is a group of numbers and variables that does include an equal sign. Once you understand these definitions, you can recognize that an equation is simply two expressions joined together by an equal sign. And, you can simplify equations and write expressions and equations.

A formula is an equation that performs a calculation. Like a calculator, Excel can execute formulas that add, subtract, multiply, and divide. One of Excel's most useful features is its ability to calculate using a cell address to represent the value in a cell. This is called using a cell reference.

Step I: Symbolize the variables of the context by a, x, A, X, etc. Step II: Use the laws or conditions of the context to establish equality (or inequality) between the variables. This equality (or inequality) between the variables is a formula for the variables . In case of equality, we get an equation.

For simple formulas, simply type the equal sign followed by the numeric values that you want to calculate and the math operators that you want to use ? the plus sign (+) to add, the minus sign (-) to subtract, the asterisk () to multiply, and the forward slash (/) to divide.

Equations are centered on the page and labeled with Arabic numerals, right-aligned, in parentheses, and referred to only by those numbers in the text ? e.g., you should always say ?as seen in (3)? rather than ?as seen in Equation (3)?.

Simple formulas always start with an equal sign (=), followed by constants that are numeric values and calculation operators such as plus (+), minus (-), asterisk(), or forward slash (/) signs. Let's take an example of a simple formula. On the worksheet, click the cell in which you want to enter the formula.

If you need to use an equation, add or write it in Word. Select Insert > Equation or press Alt + =. To use a built-in formula, select Design > Equation. To create your own, select Design > Equation > Ink Equation. Use your finger, stylus, or mouse to write your equation.

Mathematical parameters should be written in italics, (not only in the equation itself but everywhere in the thesis), but not units, numbers and mathematical functions like logarithms.
