Why is mitosis called equational division?

(N/A) Mitosis is a type of cell division in which the parent cell divides to produce two daughter cells that are genetically identical to the parent cell.
During this process,the chromosomes replicate and are distributed equally into the two daughter cells.
As a result,the chromosome number in each daughter cell remains the same as that of the parent cell (e.g.,$2n$ to $2n$).
Because the chromosome number is maintained or 'equated' in the daughter cells,mitosis is termed as equational division.
