Khamsin that was too easy. =P You can't do the same thing and just exchange a variable.
Using basic arithmetic, we can arrange 4 5s so that they equal 100 as such: (5+5)x(5+5)=100
How would you accomplish this same result using 4 7s?
I would do 77/0.77, but you can't use 0.
Yeah, but it uses 0 (in 0.77).
While you could argue that you can ignore the zero, just as you can ignore 077, 77.0, etc. the difference is that the zero in 077 is an insignificant digit, whereas the zero in 0.77 is a significant digit. So therefore, anything involving decimals is an invalid solution to this problem.
Now to find the real solution.
Another question is if they have to be whole numbers or not... If so, then your .77 won't work. But that seems like the only answer to me.
That was the only answer I came up with and had the same conclusion about the zero.
What's the only number you can spell in alphabetical order?
