Countdown Numbers Game

[Minim]

By the way, guys, this is my second attempt of making a forum game. They show this on the TV show Countdown, the longest running game show in the world. OK: I have a selection of large numbers "25, 50, 75 and 100" and small numbers "1-10" and all you need to do is combine the numbers together to write a solution with the following numbers selected using the symbols +, -, * or / to reach the target number. Brackets are allowed as well.

I hope I explained clearly enough, if not here's an example:

Target number: 846
Selected numbers: 100, 50, 8, 4, 6, 10.

First you do 8*100 which is 800 then +50 which is 850 then -4 to the 850 which makes 846.

The solution can be written like this: 8*100+50-4

You haven't explained how this is going to work as a forum game. One person sets a puzzle, the next solves it and sets the next puzzle? If so, do you want to start, since it's your idea, and I'm sure the example puzzle wasn't meant to count?

[Minim]

No. So, we'll get the game started then!

I'll start with 1 large and 5 small numbers. And remember, hide your solutions and don't cheat using the solver please!

Target number: 376

75, 7, 5, 2, 4, 5.

[Proxima]

Rather too easy:

75 x 5 + 5 - 4

Next puzzle: 972

50, 6, 7, 4, 5, 3

[Minim]

I can do 963 so far.

EDIT: Got it! Quite hard though

50*5-7=243; 243*4=972

Next puzzle: 357

25, 7, 2, 9, 5, 8.

[Proxima]

My solution was

(50 + 4) x 6 x 3

Solution to 357:

25 x (9 + 5) + 7

Next puzzle: 869

75, 3, 7, 10, 1, 4

[Minim]

869! That's a good puzzle. The best so far because other promising methods would come up close.

(3*4+75)=87; 87*10-1=869

Next puzzle: 224

25, 75, 4, 6, 8, 7.

[Proxima]

My solution was

(10 + 1) x (75 + 4)

Solution to 224:

25 x 6 + 75 + 7 - 8

Next puzzle: 605

100, 75, 2, 4, 3, 7

[Minim]

Done it! Here's one solution.

75*7+100-((2+3)*4)

Next puzzle: 284

50, 100, 3, 1, 3, 5

[Proxima]

My solution was

(3 x 100) + (4 x 75) + 7 - 2

Solution to 284:

3 x (100 - 5) - 1

Next puzzle: 346

100, 75, 7, 5, 5, 2

[Minim]

Solution is here.

75*5-(100/5+7+2)

We''l try 6 small numbers now (Evil isn't it?)

Next puzzle: 650

8, 5, 1, 6, 9, 1.

[Proxima]

Not so evil; when the target is an exact multiple of 50 it's easy to see

(9 + 1) x 5 x (8 + 6 - 1)

My solution to 346:

(100 + 75 + 5 - 7) x 2

Next puzzle: 191

25, 6, 5, 9, 5, 1

[Minim]

25*6+(9*5-5+1)

Next puzzle: 431

100, 2, 5, 4, 9, 10

[Proxima]

Not too difficult:

(100 + 10) x 4 - 9

Next puzzle: 636

100, 25, 2, 6, 2, 1

[Minim]

I came up with an interesting solution using all signs and all six numbers.

(100+6)*((25-1)/2/2)

Right then, four large and two small, if you were good at those previous puzzles.

Next puzzle: 999

100, 75, 50, 25, 10, 10.
