Enter this in C1.

=IF(AND(A1<"",B1<""),A1*B1,"")

Copy down as far as you wish.

To copy down, hover the mouse pointer over the bottom right corner of C1.
You
will see a small black cross appear. This cross is known as the "Fill
Handle"

Click on that and drag down the column.

The formula will increment automatically to

=IF(AND(A2<"",B2<""),A2*B2,"") etc.

If no numbers in A or B then the C will look blank until you enter numbers
in A
and B

Thanks. But I still feel it is too much work to do as I have to copy and
past and modify each line when I input data.
What I expected is just set the formula for the column, so every time I
fill
number to column A and B. I can get results in C automatically. Is this
possible?

In cell C1 (Or whatever cell is the first data cell if you have column
headers etc) enter the following:-

=A1*B1

or if in cell C2 then:-

=A2*B2

Copy formula to bottom

How can I set a column equate a product of two columns?
For example, I need put the product of column A and B to column C, So
that
when I input numbers to A and B, I can get their product in column C (
C=A*B)
thanks!
