The Train Game

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
