Question

Prepare a representation using digits from 1 to 10 and ÷, +, -, x, ( ), { }, [ ] such a way that the result is 100. (Use the digits only once one representation.)

Answer 1

Acc to the ques, we have to prepare a representation using digits from 1 to 10 and ÷, +, -, x, ( ), { }, [ ] such a way that the result is 100.

We can solve it a shown below:-

- 1 + 2 - 3 + 4 + 5 + 6 + 78 + 9 = 100 [This is the case where it is mandatory to use all the digits but not all the signs.]

Therefore solution is - 1 + 2 - 3 + 4 + 5 + 6 + 78 + 9 = 100 .

There are many more more ways for computation of this problem using various combinations either in reverse order or the same.
