Ah, I see. Missed that one. Thanks! That makes 46 largest so far.

]]>*EDIT: Oops...there is an example there that's just like my 21 (sorry). It's 5+1+2=8, in their daisy that goes from 1 to 25.*

From post #1's link:

You are only allowed to add neighbours (numbers touching each other) and you can only use one of each number in a sum.

Do you mean with mine, in post #16? With that one, it's 12+1+8.

If you're referring to the one in post #13, mathsyperson already made that observation in post #14.

]]>Hi guys, wouldn't it be better if there was a 20 instead of a 19 there? You can then get up to 47.

How would you make 22 and 24?

]]>Hi drdangerlove, and welcome to the forum!

I used T&E, sprinkled with a smattering of logic and system...as I described in post #9.

Thanks. I'm trying to explain different ways of working mathematically to some maths students so the ways in which these types of problems are tackled is of great interest to me.
