In mathematics, renaming is a process that involves renaming large numbers by their constituents. For example, the number 335 could be renamed to 33 tens and five ones.
Renaming is a concept in mathematics that is taught to elementary-aged school children, usually around grade three or four. It teaches students the importance of breaking three-digit whole numbers down to their tens and ones in order to do a myriad of mathematical computations. Renaming can help children estimate the answer to multiplication and division problems, compute complex subtraction and addition problems, and gain a better understanding of decimal numbers and their uses.
