Hi kalagota

Doesn't your solution give an answer of 13, as you have taken off 7 aswell as not adding it on - Aug 19th 2008, 07:19 AMkalagota
- Aug 19th 2008, 07:24 AMstevej63obviously im confused
I need to acheive an answer of 20, not 27. Using the 2, -3,-4,+5,+6,+7 or the other solution -2+3+4-5+6+7, I get an answer of 13, where am I going wrong???

(2)(3)(4)-5-6+7=20 where (2)(3)=6 (Clapping)
