Brain Quiz #14

This one took me a very long time, but odds are some of you out there will figure it out right away, and make me feel stupid. You jerks.

The goal is to get the number 24. You can ony use the simple math functions of addition, subtract, multiplication, and division. You must use every number, and you may only use each number once. There are 3 sets of numbers.. each set must be made equal to 24. 8 points for each one you get right. Get all 3 and you get another 5. Be first with all 3 and get another 5. So you can make up to 34 points on this one.

Set 1: 1, 3, 4, 6

Set 2: 3, 3, 7, 7

Set 3: 2, 3, 10, 10

Just a note, you can’t just set numbers next to each other and call it good, like putting the 1 and the 3 together and calling it a “13”. Anyway, good luck.

1. Set 3 was the easiest, wished I’d started there instead of assuming that they’d get harder as i progressed.

1: 6 / ( 1 – 3 / 4 )

2: 7 * ( 3 + 3 / 7 )

3: ( 10 – 3 ) * 2 + 10

2. Can we use parentheses?

3. Yeah, you can use parentheses to indicate ordering (first add, then multiply) that kinda thing.

4. Here’s the only one I can come up with right now. Maybe I’ll have the others later:

((10-3) * 2) + 10 = 24

5. Well, I got #2 pretty quickly, but I’ve gotten nowhere on 1 or 3, so I’m just going to post this one.

7*(3/7 + 3)=24
