The only integer solution to this question is 2 and 2 which give 4 when they are added together or multiplied together. If you do not limit yourself to integers, then any pair of numbers, x and x/(x-1) will fit the bill where x not = 1. Their sum and product are x^2 / (x-1).

The 4 numbers that give the same result when added or multiplied together are 1, 2, 3, and 6. When added together, they equal 12 (1 + 2 + 3 + 6 = 12), and when multiplied together, they also equal 12 (1 x 2 x 3 x 6 = 12). This is an example of a set of numbers that satisfy the condition of having the same sum and product.
