# Alex Bellos’s Monday puzzles

Every fortnight *The Guardian *has a mathematical puzzle by Alex Bellos. For example, this is from the puzzle for 31 December 2018:

Fill the blanks in the following equation, so that it makes arithmetical sense:

10 9 8 7 6 5 4 3 2 1 = 2019

You are allowed to use any of the basic mathematical operations, +, –, x, ÷, and as many brackets as you like.

There are various solutions, including this one: ((10 × 9 × 8) – (7 × 6) – 5) × ((4 –3) + (2 × 1))
