Using each of the numbers:
11 12 13 14 15 16
and only using basic arithmetic, it is possible to achieve the total of 987:
16 – 11 = 5
5 x 15 x 13 = 975
975 + 12 = 987
This method uses each of the numbers except for the 14.
There is a way to achieve the total of 987 by using all of the numbers once each. Can you find it?
