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?
The ages of a father and son add up to 66.
The father's age is the son's age reversed.
How old could they be? (3 possible solutions).
