since 648 = 2334 648 is divisible by any number that is 2x3y where x is between 0 and 3 and y is between 0 and 4. that gives you 20 possible answers.
NoAnswer:Adding 0 to number as in 2+0 does not change the number.Adding 0 toa number as in 2, 20, 200 ..... changes the number by 10 for each additional 0

For a number to have [only] 2 factors, it must be a prime number; the prime numbers between 0 and 20 are; 2, 3, 5, 7, 11, 13, 17, 19
composite numbers between 0-20: 4, 6, 8, 9, 10, 12, 14, 15, 16, 18

To the left of 0, between -21 on its left and -19 on its right.
Well the way I look at it is... find the total distance between the two numbers and divide by 2. so... -15 is 15 away from 0, and 20 is 20 away from 0. I then add 15 and 20 together to get 35. I take 35 and divide by 2 to get 17.5. From here you can either add 17.5 to -15 or subtract 17.5 from 20. The answer is 2.5 Another way to look at this is with a line so... each period is equal to 1 number, the 0 in the line is the number 0 -15..............0...................20 You can see that the distance is greater on the right side because 20 is farther away from 0 than -15 is. You have to find the total distance between the -15 and 20 and divide by 0.

There are 21 integers between 0 and 20, inclusive. This is because when counting the integers between two numbers, you need to include both endpoints in the count. So, in this case, you would include 0 and 20 in the count, resulting in a total of 21 integers.
