- 04 Oct '07 17:05You start with 1,000,000

You can add, multiply, divide or subtract by a number each turn.

You can use the numbers 1-9 inclusive but each only once.

You cannot use brackets.

You cannot get a fraction.

I.E if you wanted to divide by nine, you couldn't instantly. Your first moves would presumably be:

1,000,000 - 1 =

999,999 / 9 = 111,111

and then you can't use 1 or 9 from then on.

What's the lowest number you can get to? - 04 Oct '07 17:55

Thats lower than zero, pretty low! - 04 Oct '07 18:54 / 1 editThe problem was using the numbers 1-9 NOT the digits 1-9 as you did!!

Solution to 19

Its obvious to use factors of 1,000,000 first

divide by 8

divide by 4

divide by 2

divide by 5

that gives 3125

It would be nice to divide by 9 asap so

add 7 giving 3132

divide by 9 giving 348

LUCKILY thats divisible by 6

divide by 6 gives 58

We only have 1 and 3 left so

subtract 1 = 57

divide by 3 = 19

I hope I havent made any embarrassing mistake!! - 04 Oct '07 19:22 / 1 edit

Whatever that works out to be.

I think I just might be able to beat it.*Originally posted by doodinthemood***That\\\'s very good and looks fine. Impressive. I\\\'d like to see if anyone can beat that.**

Start with:

1,000,000

/8 = 125000

/2 = 62500

-4 = 62496

/6 = 10416

/7 = 1488

/3 = 496

-1 = 495

/9 = 55

/5 =**11** - 05 Oct '07 13:47 / 2 edits

Exactly how does that violate the requirements of the first post? A negative number is lower than zero in ANYONE's maths book. I can't help it if he defined the problem inexactly. If he wanted the series end to be exaclty zero he should have specified that. There was no such specification, therefore any negative number is a valid answer.*Originally posted by TheMaster37***Though what you write is complete and utter nonsense. That is exactly what math teachers are trying to get OUT of the kids heads.**

He specified, and I quote: "What is the lowest number you can get to?"

Hey, so I am lawyering up, that's what logic is all about
