Write the formula in cell E3, to calculate the total amount
Answers
Answer:
Formulas in Excel are basically mathematical expressions that use cell references (e.g., “A5”,” D17”) as arguments. For example, a formula that adds the contents of cell E5 and E6 could be written as follows:
= E5+E6
(Note: all formulas in Excel need to be preceded by an “=” sign.) If the values contained in E5 and E6 are 6 and 11, respectively, the formula will produce 17 as the value it displays. If you change E5 to 7, the result will automatically change to 18.
Example
Let's say you were putting together an office supply order, and you wanted to keep track of much you were spending. You could put together a spreadsheet like the one below, with the list of items to be purchased, their unit prices, the number of each item ordered, and the total spent for each. It would make sense to enter the things you know in advance (like the price of individual items and the number ordered), but you could let Excel calculate the totals for you. For the first item listed below (pencils), this could be done by making the value of the total price (cell D2), the value of the unit price (held in cell C2) multiplied by the number of items ordered (held in D2). This formula would be written "=B2*C2".
Excel Formula Example 1
After hitting "Enter", the cell will display the calculated value, while the formula bar will still display the formula. (Note: Always hit “Enter” when finished entering a formula, manually. If you click off the cell, the cell you click to will be added to your formula.)
Excel Formula Example 2
Excel will generally be able to handle any properly-input mathematical formula, if valid operators are used. Commonly used operators include "+" (addition), "-" (subtraction), "*" (multiplication) and "/" (division). (Microsoft has a complete list of valid operators to be used in Excel formulas on the Office website). Here are some examples of formulas using common operators:
Formula Description
=C2-B2 Subtracts contents of B2 from contents of C2
=C2/B2 Divides contents of C2 by contents of B2
=(B2+C2+D2)/3 Adds contents of B2, C2, and D2 and divides result by 3
Excel also has built-in functions that can do a lot of useful calculations. These are most easily accessed by hitting the Insert Function button, which is represented by the “fx” symbol next to the formula bar. For example, instead of entering the formula shown above, the same result could have been achieved using the built-in "PRODUCT" function by clicking in cell D2 and hitting the Insert Formula button. This would give a dialog box like the one shown, below.
