The Numbers

Time to intrigue your colleagues or customers with a number puzzle that is deceptively clever. It has been said by many wise businessmen that it is all about the numbers and what this exercise demonstrates is the numbers don’t always add up.

Guide lines
Ready, Steady, Go!

Print or hand-write the following set of numbers below one another on a piece of paper:

1000 30 1020 1000 40 1000 10

When you are ready take out the paper with the numbers. Use another piece of paper or notepad to reveal only one line of the numbers at a time.

You:

You up for a bit of counting? Nothing too tricky, just add up the following numbers as I reveal them… and give me the answer?

Lend me your ears

You should see them start to concentrate as soon as the first number is revealed.

You:

Here we go…

Reveal the numbers one line at a time, nodding and acknowledging each time they get the correct answer.

Seal the Deal and Reveal

Then reveal the last number: 10. They should give you their total: 5000.

You:

Sorry, 4100. It works just about every time.

They may want to run through the numbers again. Reveal how the final tally is in fact 4100.

You:

So close.

This should create a knowing nod or smile.

Give them the numbered piece of paper to try out for themselves on another person.

Some extra lines you can try

  • Hey, maths can be a puzzle at the best of times.
  • Just don’t use this as an excuse with the taxman.
  • That’s life - sometimes the numbers don’t add up.
Alternative ending

If available on your computer, use a text to audio option that enables your computer to read out the numbers in a Stephen Hawking computer voice.

You:

Even Stephen Hawking would have to concentrate to get this one right.

How does that work?

If Einstein were still around we could try ask him.

Anyone ever get it right?

Only a few people. But 9 out of 10 they do what you and I just did.

Who comes up with this stuff?

Again, only Einstein may know.
