42 = 4x4 = 161+2+3+4+3+2+1 = 16(3-1) x (2x4) = 16
How about: 2*(1+3+4) = 16
2/3 × 16 = 2/3 × 16/1 = (2×16)/(3×1) = 32/3 = 10⅔
16/24 because 1/3 of 24=8 so 2/3 of 24 is 16 and this caculation uses all the numbers.
1 + 2 + 3 + 4 + 9 + 10 + 15 + 16 - 5 - 6 - 7 - 8 = 34
(3 + 1)2 = 16
(4 x 3) + 2 + 1 +1 = 16
(4 + 3 + 1) x 2 = 16
3-1=2 then 2x2x4=16.
42 = 4x4 = 161+2+3+4+3+2+1 = 16(3-1) x (2x4) = 16
1 + (2 + 5)(16 + 8)/3 (1 + 2) - (1 - 6)
How about: 2*(1+3+4) = 16
only using the numbers once
2/3 × 16 = 2/3 × 16/1 = (2×16)/(3×1) = 32/3 = 10⅔
16/24 because 1/3 of 24=8 so 2/3 of 24 is 16 and this caculation uses all the numbers.
1 + 2 + 3 + 4 + 9 + 10 + 15 + 16 - 5 - 6 - 7 - 8 = 34
3-1=2 2*4=8 8*2=16 or 3-1=2 2*2=4 4*4=16
