2468 is even. Even number is another name for positive even number in mathematics. Mathematically, as opposed to odd numbers (positive odd numbers), it can be expressed as 2n numbers (n is an integer greater than or equal to 1), and even numbers must be divisible by 2. It is worth noting that 0 is not an even number (as stipulated by the International Mathematical Association in 2002 and China in 2004), because 0 is not a positive number.

Math:

Mathematics is a subject that studies concepts such as quantity, structure, change, space and information. Mathematics is a universal means for human beings to strictly describe the abstract structure and mode of things, and can be applied to any problem in the real world. All mathematical objects are artificially defined in essence. In this sense, mathematics belongs to formal science, not natural science. Different mathematicians and philosophers have a series of views on the exact scope and definition of mathematics.
