Thank you very much.

00:01:01,500 --> 00:02:17,689
we put together the three numbers to see what happens then we ask them to put together the three quantities

00:02:17,689 --> 00:02:22,830
so they will put together the three quantities

00:02:22,830 --> 00:04:23,370
I'm going to show you how to do it.
