This is a great puzzle which the Guardian ran last week:
Fill in the equations below using any of the basic mathematical operations, +, –, x, ÷, and as many brackets as you like, so that they make arithmetical sense.
10 9 8 7 6 5 4 3 2 1 = 2017
There are many different ways of solving this – see if you can find the simplest way!
Scroll down to see some possible answers.
I had a play around with this and this is my effort:
(10+(9 x 8 x 7) -(6 + 5) ) x 4 + 3 + (2 x 1) = 2017
An even nicer answer was provided on the Guardian – which doesn’t even need brackets:
10 x 9 x 8 x 7 / 6 / 5 x 4 x 3 + 2 – 1 = 2017
Any other solutions?
