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.
If it ain't broke, fix it until it is.
A number by itself is useful, but it is far more useful to know how accurate or certain that number is.
