Dear All,

7  0  5

2  6  4  4

In the above two expressions, use mathematical signs / operators from among the four basic signs ( + , - , * , / ) that is addition, subtraction, multiplication, divisi0n and power ^, factorial !, decimal . Total number of signs / symbols used in the two expressions combined shall be three or less.  Concatenation that is clubbing of digits is allowd. That means you can club digits 7 and 0 to 70. You should not change the order of the digits.

Now bring the above two expressions as close as possible in value, but not equal.  You may use bracket signs ( in addition to the three signs allowed ) for convenience.

What is the closest you can come ?

EXAMPLE :

70 + 5 = 75

26 + 4 4  = 70

total number of signs used is 2.

The first  expression ( 75 ) is 7.15 % higher than the first ( 70 ).

How much closer can you come ?

good luck!
