The sum is 75.
The answer is 28
The sum of the five odd numbers between 10 and 20 is: sum = 5 x (11 + 19) / 2 = 75.
The composite numbers in that range are 10, 12, 14, 15, 16, 18, 20. I don't know if you're including 10 and 20 or not. Add them up however you like.
It is 0.5
The sum is 75.
The sum of -5 and 20 is 15. The distance between -5 and 20 is 25. The sum of the numbers between -5 and 20 is 180. The sum of the numbers from -5 to 20 is 195.
well, let's break it down. First, the even numbers between 1 and 11 are, 2,4,6,8,10. Now 2+4=6, 6+6=12, 8+12=20, 20+10=30. So, to answer your question simply, the sum of even numbers between 1 and 11, is 30.

-20
It is 0.5
The numbers are 30 and 20.
20 number
The sum of two numbers between 20-40 is 58. The difference is 12
The sum is the result you get when you add two or more numbers together. A single number can be the sum of two or more other numbers when they are added together but cannot be expressed as you ask in your question. Though you could ask "What numbers have the sum of 20?" For instance 20 is the sum of (10 + 10), (5 + 15), (2 + 7 + 11) etc., but is not in itself a sum.
