To find two numbers that add up to 18, we can set up an algebraic equation. Let's call the two numbers x and y. The equation we need to solve is x + y = 18. Since we are looking for two numbers that add up to 18, there are multiple possible solutions. For example, one possible pair of numbers that add up to 18 is 10 and 8, as 10 + 8 = 18.

Well, honey, first you multiply the sum and difference of the two terms to get the difference of squares. Then you factor that bad boy into two binomials. Finally, you just simplify and voila, you've solved the product of sum and difference of two terms. Easy peasy, lemon squeezy!

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

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.
