A number in standard form is just the same way you are always used to seeing it. Like for example: 256. To write that same number using expanded notation, you have to think of the place values of each of the digits. The number is the sum of those values. 256 = (2 x 100) + (5 x 10) + (6 x 1). That's 256 in expanded notation.
256 = (2 x 102) + (5 x 101) + (6 x 100) OR (2 x 100) + (5 x 10) + (6 x 1).
256 is equivalent to magana mere na mirongo ithano na ithathatu in Kikuyu language.
