n a hotel, a man was sleeping when he heard a knock on the door. He shifted the blanket and stepped down from the bed. He waked to the door and opened it to find a stranger standing outside.

We can create number 100 by using all numbers, i.e.0123456789 and mathematical operators (+/-) in many ways.

Example

98 + 7 + 6 - 5 - 4 - 3 + 2 - 1 = 100

But if we add a condition that the use of the number 21 is the must. Then there are only a few solutions.

One of such solution is:

98 - 7 - 6 - 5 - 4 + 3 + 21 = 100

Can you tell any other solution?
