Puzzle 5
Complete this grid with the digits 1 to 6 to make the sum correct.
Perform each mathematical operation in the order shown, from left to right, so 1 + 2 x 3 is treated as (1 + 2) x 3 = 9.
Consecutive numbers are not next to each other, there is no ÷ 1, and at no point is a decimal or a fraction used.
Note: this puzzle is not interactive, and the squares cannot be clicked.
