Re: crack this triangle

Hi sathru;

Welcome to the forum. What do they want? The next row? One particular number?


In mathematics, you don't understand things. You just get used to them.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.
