When Excel establishes a financial report, it is usually necessary to calculate the relevant data, which is where we use the Excel program to facilitate the language. In the calculation of data, you need to establish a formula to achieve, and in the use of the formula, you need to refer to the value of the cell to calculate, then in Excel how to use the
Sometimes we have a royalty formula for each product, and the formula used for this calculation exists in the table in the string format. when we use this formula, it is not like the one we wrote: $ a2 + 3*5; in this way, the result can be calculated simply, and it is a string. therefore, we must convert the string int
