# Ten Digits And Operator Puzzle

1. Aug 1, 2008

### K Sengupta

Using each of the ten digits 0 to 9 exactly once, and using only the arithmetic operators: addition(+), subtraction(-), division(/), multiplication(*) and parentheses, generate an expression that equals 975.

Note:

Concatenation of two or more digits is permissible, so that, expressions like:
12*(4/3) + 56-78+9 = 3 are permissible.

However, utilization of exponentiation(^), factorial(!), or other mathematical expressions is not allowed.

For example, expressions like: 1834567^0 + 2! = 2 are not valid.

975 + (0 * 123468)
Of course, this is only one of a very large number of solutions.

One solution:

(89-76)*450/(1+2+3) = 975

I hate when that happens. And it happens all the time.
