On a blackboard in a classroom an equation had been written, but someone had rubbed out all but three of the digits. All that was left was
28? + ??4 = ????
The teacher who had written the equation could remember that all ten digits 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9 were used in the equation.
Can you recreate the equation?
The original equation was
289 + 764 = 1053
