The two numbers that add to give you 18 and multiply to give you 40 are 10 and 8. This is because 10 + 8 = 18 and 10 x 8 = 80. However, if the question is referring to two numbers that add to 18 and multiply to 40, the correct pair would be 5 and 8, as 5 + 8 = 13 and 5 x 8 = 40.
You multiply them.
The first 12 are: 60, 120, 180, 240, 300, 360, 420, 480, 540, 600, 660 . . .

Multiply each one by each of the others (separately), add them together and multiply by 2. 140*120=16800 140*4=560 120*4=480 16800+560+480=17840 17840*2=35680 units squared
The two numbers that add to give you 25 and multiply to give you 26 are 24 and 1. When you add 24 and 1, you get 25, and when you multiply them, you get 26.
