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.)

What is the properties of complex numbers when you are considering it in case of group?
The properties of an array or group or complex numbers form a system of real and imanginary numbers that are at a 90 degree angle to each other. Refer to the Related Link and notice that in both panes, the lines are at 90 degrees.
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...
How will making an array help someone find factors in a number?
The numbers of rows and columns in a rectangular array form a factor pair for that number.
What does the word array mean in math?
An array is a set of numbers that form some sort of regular arrangement. A linear array is a 1-dimensional array consisting of a row or a column of a set of numbers. A 2-dimensional array is a rectangular arrangement of numbers. And there are arrays with higher dimensions. The elements of an array need not be numbers: they could be variables, functions or expressions. In other words, it's a picture to describe a multiplication problem.
The definition of rectangular array?
An arrangement of objects into rows and columns that form a rectangle. All rows and columns must be filled . Each row has the same number of objects and each column has the same number of objects. -Danielle German Grade 6
What is a rectangular number?
A rectangular umber is essentially a composite or non-prime number. If a number n is composite then it can be factorised as p*q. In that case, it can be represented as an array of p rows and q columns in a RECTANGULAR array.
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.
What is the formula of rectangular numbers?
Rectangular numbers are of the form n(n+1) for n = 1, 2, 3, 4, 5, 6, ... The first few rectangular numbers are: 2, 6, 12, 20, 30, 42, ...
Is it possible to declare an array of numbers in an integer form?
Yes: int[] integerArray;
Are prime numbers rectangular in shape?
No, they are the only numbers that are NOT rectangular in shape. (I think you knew this and screwed up your question.) That is, all non-primes can be arranged into the form of a rectangle - e.g. 21 can be organized as a rectangle with dimensions of 3 x 7. But prime numbers cannot be organized as rectangles.
How do you find base of a rectangular prism?
