Let us use the mathematical functions in Excel 2016.
Perform the following steps to use the mathematical functions:
Step 1 Type the given data in the Excel 2016
worksheet.
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, price of the pencils
appears in the cell D3. Using the AutoFill feature, we Using PRODUCT function
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. Using SUM function
Step 6 Calculate the Tax by using the =(D6*7)/100
formula in cell D7.
Step 7 Calculate the Total by using the
=SUM(D6:D7) function in cell D8. Final
output appears as shown:
