Detailed explanation-1: -A formula always starts with an equal sign (=), which can be followed by numbers, math operators (such as a plus or minus sign), and functions, which can really expand the power of a formula. For example, the following formula multiplies 2 by 3 and then adds 5 to that result to come up with the answer, 11.

Detailed explanation-2: -All formulas begin with an equal sign (=). You can create a simple formula by using constant and calculation operator. For example, the formula =5+2*3, multiplies two numbers and then adds a number to the result. When you want to refer to variables instead of constants, you can use cell values, for example, =A1+A2.

Detailed explanation-3: -An equation is a mathematical statement where the equal sign is used to show equivalence between a number or expression on one side of the equal sign to the number or expression on the other side of the equal sign. Every equation has two sides (i.e., left and right).

Detailed explanation-4: -All Excel formulas begin with an equals sign, =, followed by a specific tag denoting the formula.
