Enter data in column A and column B in turn, as shown in the figure below.
Move the cursor to C 1, as shown.
Enter =A 1*B 1 in the calculation column (the symbol in the middle is the operation symbol). We have to calculate multiplication, so we play multiplication symbols (addition, subtraction, multiplication, Divison symbol on the keyboard).
Press enter to exit.
Place the cursor in the lower right corner of C 1. When the cursor changes to a black cross, press the left key and drag it down.
