Incredible Mental Math Gymnastics on â€śCountdownâ€ť

CountÂ­down is a British TV game show revolvÂ­ing around words and numÂ­bers. In the numÂ­bers round, conÂ­tesÂ­tants select six of twenÂ­ty-four shufÂ­fled tiles with numÂ­bers on them. Next, a comÂ­putÂ­er genÂ­erÂ­ates a ranÂ­dom three-digÂ­it tarÂ­get numÂ­ber and the conÂ­tesÂ­tants have thirÂ­ty secÂ­onds to get as close to that numÂ­ber as posÂ­siÂ­ble by comÂ­binÂ­ing the six numÂ­bers through addiÂ­tion, subÂ­tracÂ­tion, mulÂ­tiÂ­pliÂ­caÂ­tion and diviÂ­sion. This memÂ­oÂ­rable episode of CountÂ­down aired in March 1997 and starred James MarÂ­tin and his rather unusuÂ­al way of arrivÂ­ing at the tarÂ­get numÂ­ber of 952.

One YouTube user sugÂ­gestÂ­ed a difÂ­ferÂ­ent way: 6 x 75 = 450; 450 Ă· 50 = 9; 100 + 3 = 103; 9 x 103 = 927; 927 + 25 = 952

I found yet anothÂ­er way: 100 + 3 = 103; 103 x 6 = 618; 618 x 75 = 46,350; 46,350 Ă· 50 = 927; 927 + 25 = 952

What about you? Any more sugÂ­gesÂ­tions?
