24
21+3 or using all the numbers: 21 + (3*(2-1))
106------------------------------------------------------------------------------------------------From Rafaelrz.You can make, 4P3 = 4!/(4-3)! = 24, different 3 digit numbers using 1, 2, 3 and 4.
5! / 4 - 2 * 3
By using: (3*6)+(3*2) = 24
3*3 + 3*5 = 9 + 15 = 24
Assuming I have to use all 4 numbers: 3 x 9 + 5 - 8 = 24
(5+7)*(5-3)=12*2=24
Yes. 6*(5 - 3)*2 = 6*2*2 = 12*2 = 24
4*3*2 = 24 of them.
8x3=24 24+3-3=24
8/(3-(8/3))=8/(1/3)=24 :d
