You must do the multiplication before the addition
(3)5+6/1=15+6=21
acharpe said:6/(1-(5/7)) = 21
That makes it become 6/(2/7) which would then become 6*7/2 which would make 21.
golfcigarjunkie said:I stand corrected 21 was not part of the orginal numbers it was the answer we were to use 1,5,6,7 to get an answer of 21.
