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).
5+5 By quadratic equation the two numbers (roots) are: 8.872983346 and 1.127016653 Added together = 10 Multiplied = 10
1, 2 and 3
One, two, and three.
Two (or four) digits added together cannot equal 42. Two-digit numbers multiplied together cannot equal 82.
The numbers are 10 and 5.2
