In the last blogpost I challenged all you number-heads with this sum:
Add, subtract, multiply or divide the following six numbers 2 7 25 50 75 100 to get 265.
You notice that it contains all the big numbers and two small.
In an update I hinted that 5 was a key number in the solution.
It's also worth noting that 265 = 250 + 15.
Now watch the solution:
265 = (50 x 25 + 75) / (7 - 2) = ((50 x 25) / 5) + (75 / 5) = 250 + 15
