Right. I kinow what you mean by that and you may well have put the right number at the top, but

it is a good idea to try to avoid putting something like " 9 x 9 = 1 " because although it is indeed 1

that we are trying to get here strictly speaking 9 x 9 is 81.

You can probably see that the answer at the top becomes: 0 8 3 1 so the answer is 831.

Shall we try a multiplication for a change how about 683 x 6 ?

First of all how should we lay out this multiplication ?

He might sneak in. He is a spammer. Do not worry about him,.

_____That one is wrong, but it is not too far out. You have I think made a minor error with either

the carry of 3 x 7 = 21 and carried a "1" instead of "2". Or maybe you accidentally put in

7 x 2 as 13 rather than 14. The number at the top in the middle bit you have put as " 1 5 1 ".

What did you carry at each stage in this bit ? Do you want to try that bit of it again ?3 6

________Very good again, although you have written them a bit out of alignment on the screen you

have got all of the middle bits correct and added them correctly.So you may wish to just look at the first one and see the mistake you made in the first middle number.

The " 1 6 1 " bit is now correct. Well done.

Now because the answer depends upon this bit being correct you should really redo the addition.

In other words what effect does this have on the final answer ?

Right now according to what I have read on something you wrote to me about earlier your next topic

is "Factors and Multiples". Is that the one that you consider to be next. Or is there something else ?
