A number that can only form one rectangular array would be one that has only two factors, which means it is a Prime number. The factor pairs show the different rectangular arrays that can be formed.
2 = 1 x 2
3 = 1 x 3
5 = 1 x 5
7 = 1 x 7
4 = 1 x 4 and 2 x 2, so it can form two.
6 = 1 x 6 and 2 x 3, so it can form two.
8 = 1 x 8 and 2 x 4, so it can form two.
9 = 1 x 9 and 3 x 3, so it can form two.
10 = 1 x 10 and 2 x 5, so it can form two.

What is an array diagram in math?
An array diagram is a way of representing information in the form of a rectangular layout or in analogous shapes in higher dimensions: cuboids or hyper-cuboids.
Why can't we add and subtract polar form of complex numbers and multiply and divide the rectangular form of complex number?
You can certainly multiply and divide with the rectangular form, but it is somewhat easier in polar form. This is especially relevant if you want to extend to more complicated operations, such as higher powers or taking roots. As for the polar form, any method to add and subtract them directly would probably be quite complicated, and directly or indirectly involve many of the same calculations that are done in converting from polar to rectangular, and back. Try it! (That is, try to deduce the formulas for adding two complex numbers in polar form.)

How many rectangular arrays can be formed with 24 tiles?
Well, honey, let me break it down for you. To form a rectangular array, you need to find pairs of factors of 24. So, 1 x 24, 2 x 12, 3 x 8, and 4 x 6. That's a total of 4 rectangular arrays you can make with 24 tiles. Math can be sassy too, you know!
What numbers are between 0 and 1?
There is an infinity of numbers between 0 and 1. In decimal form, all of then would have the representation 0.abcd...
