Make 24

100

4, 5, 9, 6

4+5+6+9=24

200

4, 9, 3, 4

4*9-3*4 = 36-12 = 24

300

5, 6, 7, 8

6*8=48

7-5=2

48/2=24

500

3, 8, 3, 8

3 - (8/3) = 1/3

8/ 1/3 = 8*3 = 24

Countdown(randomized scoring)

100

Make 150 with 300, 3, 5, 5, 5, 3

5+5 = 10, 10/5 = 2, 3-3=0, 2+0=2, 300/2 = 150

or 

3*5*5*(5-3) = 150, 300 - 150 = 150

200

Make 205 with 3, 4, 4, 7, 25, 100

4 * 3 = 12, 12 - 7 = 5, 25 * 4 = 100, 100 + 100 + 5 = 205

300

Make 647 with 3, 3, 6, 25, 75, 100

75 / 3 = 25, 25 + 25 = 50, 50 - 3 = 47, 100 * 6 = 600, 600 + 47 = 647

500

Make 356 with 75, 9, 5, 5, 10, 2

10 - 5 = 5                                                    2*5+9 = 19

5*75-19 = 356
