There are infinitely many numbers between any two different numbers. To get the number that is exactly in the middle, add the two numbers, then divide the result by 2.

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
The number that is greater than 12 but less than 40 and has exactly 3 digits is 13. This number fits the criteria because it is greater than 12 and less than 40, and it has three digits (1, 3, and 0). It is the smallest 3-digit number that meets the specified conditions.

There are an infinite number of them.Here are a few:3.0000000013.000000013.0000013.000013.00013.0013.013.13.23.94.14.44.84.94.994.9994.99994.999914.99992..etc.The number that's exactly half-way between 3 and 5 is 4.It's also called the 'average' of 3 and 5.
The prime numbers between 0 and 10 are:2, 3, 5, 7.
There are infinite numbers between 1/3 and 1/4, but the number exactly halfway between them is 7/24.
The absolute value is the "magnitude" of a number relative to 0. In real numbers, this is essentially the distance between a number from 0 on the number line. For example, -3 is 3 integers from 0, so |-3| or abs(-3) = 3. 3 is also 3 integers from 0, so |3| or abs(3) = 3 as well. |0| = 0. In complex numbers a + ib, | | is defined as sqrt(a2 + b2).
The number is 3.
exactly in the middle between 1 and 5 is 3, and between 4 and 5 is 4.5
