What operations are you allowed to use? Are you only allowed to use addition? Or is subtraction, multiplication, or division also allowed?
Here goes. I have to achieve the highest number possible equal to or less than 143. 143 is the ideal number, anything above that is of no use. The numbers I have to work with are 37, 73, 44, 44, 40, 52, 73, 34 and 39. The closest I've managed to get is 140 combining 44, 44 and 52. Can anyone find anything higher than 140 or another combination that makes 140? Thanks for your help.
Right, I've had a look at my figures and there are infact some that I can subtract. So now the question is: I need to get as close to 143 as I can without going over 143. The numbers that can be added to make this number are 37, 73, 44, 44, 40, 52, 73, 34 and 39. The numbers that can be subtracted to make this number are 42, 46, 28, 28, 59, 67, 60, 52, 114, 64 and 80. So you're allowed to go to 190(for example) and subtract 52 to reach 138. Thanks for your help.
