I want to multiply an entire column, by another column, and accumulate the results. Like this:
<tbody>
</tbody>
and then sum them. the result would be the sum of all the column c = 44.
how can I do it? how can I calculate c directly? do you know a special function available for doing so?
thank you. sorry if there are some mistakes, I am not english-speaker.
A | b | c |
2 | 5 | 10 |
3 | 4 | 12 |
4 | 3 | 12 |
5 | 2 | 10 |
<tbody>
</tbody>
and then sum them. the result would be the sum of all the column c = 44.
