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.
The main operation on the cubic root is finding the value of the cubic root of a number. This is commonly represented by using the symbol ∛, such as ∛x. Other related operations include estimating the value of the cubic root, solving equations involving cubic roots, and using properties of cubic roots in mathematical calculations.

Complex numbers extend the concept of real numbers by introducing an imaginary unit, denoted as "i." Real numbers can be considered a subset of complex numbers with the imaginary part equal to zero. Complex numbers include both a real and imaginary component, allowing for operations like addition, subtraction, multiplication, and division.
Numbers go on forever. Any number can be increased by adding 1, or by adding any other number, or by doubling that number, or by multiplying that number by any other positive number greater than 1. All such operations will result in a larger number, and you may perform such operations as many times as desired. ("Infinity" is a concept different from large numbers; it is not itself a number in the class of "real numbers.") You may see the Related Link for more on large numbers.
