### are formulas and equations the same?

Your instance is an equation because every expression that begins with an equals sign is an equation. Because mathematicians enjoy using equal signs, equations are a common sight in the field. A equation is a set of steps to be followed in order to get an outcome. Chemical formulas (two H and one O make H2O) and the Coca-Cola formula are two nonmathematical instances (which is just a list of ingredients). One could argue that hydrogen and oxygen are not “equal” to water, but they can still be used to create water, therefore these examples do not constitute equations. Number theorists have known for a long time that equations are the shortest way to express certain formulas. In the case of the Pythagorean Theorem, for instance, we may represent the formula as an equation since it turns out that the length of a side of a right – angled triangle has always been equivalent to a sum of the other two strings. A crucial point is that the formula represents not only the constituent parts of the equation as well as the interdependence among them.

### what are the formulas for area and perimeter?

Perimeter (P), length (L), and width (W) are the inputs into the perimeter formula for a rectangle, which yields the answer (L + W) 2. If you are given the length and width of a rectangle, you can easily calculate its perimeter using a simple formula.

### what formulas to use in excel?

· Among the first Excel formulas you should learn, SUM is the most important. Typically, it sums data from a subset of the columns or rows in the table you’ve chosen.

· The AVERAGE function is analogous to basic averages of data, such as the average number of stockholders in a particular pool of stock.

· Cells in a specified range that solely contain numbers are tallied by the COUNT function.

· COUNTA is a function that, similar to COUNT, counts the number of cells in a range. Contrarily, it includes all cell types in its tally. As opposed to COUNT, which only counts numeric values, this function counts anything that can be represented as a string, including dates, times, logical values, errors, an empty string, or text.

· Sorting data according to predetermined criteria is a common use for the IF function. What makes the IF formula so great is that it can host other formulae and functions within itself.

· The TRIM function guarantees that your functions will not fail as a result of trailing space characters. It guarantees that there are no voids left. TRIM is specific to a single cell, as opposed to other activities that can affect several cells. As a result, you’ll have to deal with the drawback of having to enter the same information twice into your spreadsheet.

· When looking for the highest or lowest value in a certain range, you can use the MAX and MIN methods, respectively.
