1 1/2 one and a half
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
30. 60. 90
NO!NOTE: There is a trick involved here ... to find if a number is divisible by 3, add all the digits together (in this case, 1+0+4+7+4 = 16.)16 is not exactly divisible by 3, so 10474 is not either!

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
