i thought you had been chosing prime targets or odd multiples of primes and only giving us even numbers to make it hard, which it has been!

dunno how they do it without the calculator :eek:

2 3 5 25 25 100

(50+4) x (2+7) - 7 = 479

Do you have to use all the numbers? cos I didnt use '1' in that solution.

• Registered Users Posts: 1,328 ✭✭✭

(2x3x5x25) - (100/25) = 746

anyway, going to be slightly presumptuous here and pose this one:

2 2 6 10 50 100

Target: 473

( 10 * 50 ) - ( ( 100 / (6 - 2) ) + 2 ) = 473

(7+7) * 2 = 28 + 2 + 1 = 31 * 25 = 775

(I'm sure that someone else saw this already, but since nobody else posted )

(1+7) *25 = 200

(200 - 7) * (2*2) = 772

I think thats probably the closest.

9 * (75 - 1) - ( 10 * 2) maybe?

• Registered Users Posts: 2,076 ✭✭✭

(75 - 10) * (9 + 1) - 4 = 646

3, 2, 6, 4, 3, 50

(50*3)-6-4-3=137

((50+8)*(10+5))-25+4=849

100, 25, 6, 9, 2, 3 -> 573

(100x6) - 25 - 2 = 573

This is tough, but doable.
