gonna apologise in advance in case this game is perceived as really nerdy

i learnt this one when i moved to sydney

each carriage of a train in sydney has an identification number just in case of an emergency or something.

so there's normally about 5 digits i think and the game is to basically try and use the 5 digits to make the target number using addition, subtraction, division and multiplication.

if you've seen the show Letters & Numbers it's like the numbers bit.

once someone's figured out the above one post another one for the next person to do. just make sure it's possible though !

eg. TARGET = 18

DIGITS : 5 3 2 5 2

ANSWER 5 + ( 3 x 2 ) + 5 + 2 = 18

* there might be others, i don't know

so the first one is ....

(1) DIGITS : 1 2 3 4 5

TARGET = 5
