## anonymous 5 years ago if you have four 1's.what is the largest number you can make.(you can use any operator...+,-* etc)

1. anonymous

i think it should just be 4

2. anonymous

it is 4

3. anonymous

sorry..its not...try again

4. anonymous

either 1+1+1+1 or (1+1)(1+1)

5. anonymous

no..

6. anonymous

hint:any mathematical sign you can use

7. nowhereman

Then there is no biggest one, you can always take the factorial: (1+1+1+1)!!!!!!!!!!.. and so on

8. anonymous

no

9. anonymous

try again

10. anonymous

yes,nowhereman,u are corrrect

11. anonymous

12. nowhereman

So if decimal system is allowed, why is factorial not? That's really arbitrary. If you want to make this a fair question you have to list which operations are allowed.

13. anonymous

i have just used the power.. 11 to the power 11

14. anonymous

use factorial but it will be a smaller no.

15. nowhereman

No it won't: $(1+1+1+1) = 4, \quad 4! = 24$$(1+1+1+1)!! = 24! = 620448401733239439360000 > 285311670611 = 11^{11}$

16. anonymous

11*11=121

17. anonymous

no fairy.. its 11 to the power 11
