11 and 7 Add them and you get 18, subtract them and you get 4.
subtract the biggest # from the lowest. If you the numbers 10, 18, 2, and 20, to find the range you would do this: 20-2=18. So the range would be 18.

Let's denote the two numbers as x and y. We can set up a system of equations: x + y = 18 and x - y = 4. By solving this system simultaneously, we can find that x = 11 and y = 7. Therefore, the two numbers that add up to 18 and subtract to 4 are 11 and 7.

well that is easy to add two whole numbers like 8+10 is just 18 so you find the total of the two numbers. then to subtract you take it away so 9-4=5 then to check add the 2nd number (in this case 4) to what the sum equals and 4+5=9

22 and 18
The two numbers that add up to -36 and multiply to 324 are -18 and -18. This is because -18 + -18 equals -36, and -18 * -18 equals 324.
