Ants, got in there before me - and another 5 number game

9 * 8 = 72
72 * 2 = 144
6 * 5 =30
144 - 30 = 114

same set from me

I can only get 736, I don't think that is possible.

I know we always try to think of difficult ones, but they all usually come with 6 numbers, but I'll do this one in 4 Carol

Ooops, sorry about that. Off by one error in my code.

Same here, I can only get 736. I think the anomaly lies in the fact all the integers are even and the target is odd. The only way to get an odd number from a load of even numbers is to do the trick I used up above which i also don't think is possible this time round.

I haven't got an answer for the above but I said I'd throw a link on here for ye - might be interested.

There's an official Countdown app on iOS but all the Android ones I found are a bit off. A guy in my class developed one for his FYP and here's the link - he's not making money from it so this is genuinely just because I thought you folks might like it!

Now back to try solve that numbers game...

Am I not allowed to do that. What i mean is dividing 50 and multiplying by 75. Or dividing by two thirds. I suppose could have multiplied by 75 and divided by 50 would have got same result i think. Tar.Aldarion does not make it easy

By the way. Do I need to make sure there is a solution to them before posting? there def to this one anyway. be nice to save the time though working it out.

FatFrog87, number of issues with your above post, so first of a valid solution to the one above, as you can only use +, -, / & *, no other calculations

5 - 4 = 1
6 + 1 = 7
50 - 1 = 49
49 * 7 = 343

Also, your 6 numbers, you can only have one of 25, 50, 75 & 100, you can then have 2 of 1 - 10 otherwise, would have a crack at them myself

25 * 8 =200
200 + 25 = 225

225 - 3 = 222
