I saw this in a newspaper – it was a puzzle for adults, fully grown humans, but I think you will find it easy.


All the digits from 1 to 9 are used in this grid, but only once. Can you work out their positions in the grid so that each of the six different sums work?


Two of the numbers have been inserted in order to get you started. Just identify the other seven numbers.


(NOTE: perform operations in the order they appear, e.g., 3+4×5=35 (not 23))
a=
b=
c=
d=
e=
f=
