Tech Fact
In functions, we can also use the cell address in place of the values.
Let us use the mathematical functions in Excel.
Perform the following steps to use the mathematical functions:
Step 1: Type the data in the Excel worksheet as shown here..
Step 2: To calculate the price of Pencils, type the =PRODUCT(B3:C3) function in the cell D3.
Step 3: Press the Enter key from the keyboard.
When you press the Enter key, the price of the pencils appears in cell D3. Using the Auto Fill feature,
we can calculate the prices of the Geometry Boxes and Pens.
Step 4: To calculate the subtotal, type the =SUM(D3:D5) in the cell D6.
Step 5: Press the Enter key from the keyboard.
When you press the Enter key, subtotal appears in the cell D6.
Step 6: Calculate the Tax by using the =(D6*7)/100 formula.
