Using the numbers 3,3,7 and 7, try to make 24, using additon, subtraction, multiplication and division. You must use all four numbers.

If you already know the answer, don't bother posting. Let people work it out for themselves.

Do you have to use them in the sequence you provided, or can you change the order of the numbers?

EDIT: How many times can you use each number?

Beowulf · Post by **Beowulf** » Wed May 22, 2002 12:15 pm

Any combination, once you use all four numbers. Except things like 7^2/7. That counts as using seven three times

EDIT: You use three twice, and seven twice.

Try this:

If you are allowed to use decimal points then
.7 + .3 + 7 * 3 = 24

The solution is simpler than that

3-7 = -4; 3x7 = 21; -4+21=17; 17+7=24

is that too many sevens?

Do you have to use all the numbers? (Cos it's really quite simple with 3, 3, and 7.

)

@froggy you used three 7s

I think this works:

(3/7 + 3)*7 = 24

I couldn't get one and I spent far too long thinking - almost a minute

(3/7 + 3)*7 = 24

Ladies and gentlemen, we have a winner.

Damn, I was hoping it would drive the population of SYM insane, somehow destabilizing the $US, which would allow me to take over the world
