On the eve of this year, I thought of coming up with a mathematical expression to represent the new year 2020. The plan is to use the digits from 0 to 9, each used mandatorily and only once in descending order. After a few attempts, I found the following :

$latex \frac{( 9\times 8) -7-6+5-4}{3} \ ||\ ( 2\times 1) \ ||\ ( 0) &s=3$

[Here || stands for the concatenation operator]
