Hello, Everyone.

Simplify A ?

Thanks in advance for your time and help.

Best Regards.

Even simpler like this. While I think that Mathcad should be able to simplify it in exact mode.

Notice that I formatted the expession using the Result Format menu, otherwise the 120 would show as 199.9999999....

See below how to prove with Mathcad in exact mode that the coefficients 60 and -120 are exact.

Mathcad is able to do it in exact mode, all it needs is a ridiculous simple help (it should not be necessary):

BTW, don't bother with Valery's file - it's in Prime format and he is just joking around - thats the whole content:

Many thanks for your response, Viktor and Valery.

Valery, my Mathcad 14 can not open your file.

Viktor, give me a time.

Best Regards.

Loi.

No, as already said, using float means you are leaving the road of exact results. Thats the reason for my efforts to avoid float in symbolics. Nevertheless the first float was necessary to see what the result could be and to suspect that 60, 12 and 120 could be the exact results.

BTW, Mathcad won't factor for non integers anyway.
