Applying BODMAS rules, we should start with multiplication. The quotient of the first two digits has to be lower than 14, as we will need to add more digits later.
In determining the most prudent digits to use for these positions, we can take advantage of the unique properties of the number 1, enabling us to twin it with a high number. For example, we can choose 9, and divide it by 1 to arrive at 9 - a number close enough to our predefined result that simple addition can get us to it.
9 + x + y = 14
Next, we will use inverse operations on both sides of the equation to simplify it:
x + y = 5.
All that remains is to find an appropriate combination for X and Y. One possible combination is: (3, 2).
Therefore, a possible solution is: (9, 1, 3, 2)
Other possible solutions: (8, 4, 9, 3), (5, 1, 6, 3).
