Mind Bender # 3 : The Versatile No. 7

A few people suggested the last Mind Bender might have been too easy. So, here’s something to mull on over the weekend.

A large part of your success will come from your ability to combine the familiar aspects of what you deal with, in a completely new and more profitable way.

You’re no doubt familiar with the No. 7. And for many people, it’s their lucky number. But you probably don’t realise how versatile it can also be, in creating other numbers as well.

For this Mind Bender, what you need to do is … combine four 7s together (using whatever mathematical symbols you may need) to try to create the whole numbers between 1 & 20.

Let me give you a few examples …

1 = 77/77

2 = 7/7 + 7/7

20 = 7/.7 + 7/.7

Your challenge now is to continue combining four 7s … and try to discover which number (between 1 and 20) cannot be created in this way.

Here’s a table you can download – to make it easy for you to fill in your workings.

And then, once you’ve gone as far as you can … just email me through your answers.
