What is the biggest number you can make by moving exactly 2 matches in the number above?
Assume that numbers must be represented in their standard “digital clock” font (for example, a “1” requires two segments).
Solution
81151 is the biggest number.
The trick is you are not limited to just 3 digits! Break the “0” into two ones, and use those two matches to create a new “1” before the 5 (which gives you 15118). Then turn your head and view the whole thing upside-down:

(If you consider changing your perspective an unfair gimmick, 51181 would be the biggest number you could make.)

U r not exactly moving 2 matchsticks u r moving 4??
The answer is NOT 81151. Turning it upside down is moving ALL the matchsticks. The non-trick answer is 51181.
The idea is you turn your head around and view it from a different angle, rather than moving any matchsticks. But your perspective (that this is a gimmick or a trick) is equally valid.
The answer is 8118
my answer is 51181 , there has to be two matches to create the number one!!
correct
The highest number I can see is 151,181. There is no rule in the directions that says a number 1 has to be two matches in length.
The directions do state that a β1β requires two segments.

90E77 (90 to the power of 77) for a beginning. I expect there are better solutions based on this principle.
51181
