[jow104]

Minus 10

How do you do this physically to proove.

i.e. how can you lay down minus ten pieces and then carry on the clculation?

[echnidna]

do the calculation with any other minus number and the end result will be 7.

[jow104]

Bob I mean to have physcially have minus ten pieces or any other minus number of pieces, and then to display it not in an oral or verbal manner.

[Skew ChiDAMN!!]

Don't you have the concept of bills in England?

I think 'tis time for me to emigrate...

[echnidna]

and then to display it not in an oral or verbal manner.

Can I relate it to you this way

Measure a length of Timber.
Starting half way along, let this be your Reference point;
otherwise known as Zero (Point).

What ever is one side is +ve,
on the other side is -ve.

How far from it is the size of the number, depending what unites you measure in.

Move the reference point [ZERO]

and you change the size of the number which are +ve,
Ditto -ve


Far from the ideal way to explain

Blocklayer, that was a good post and link.
Tell us please how you made that calculator.

Ivan, I was thinking along the lines of the Dimbleby science lectures that the British BBC does at Xmas time, they do practical/physical illustrations.
