Numbers can be written in decomposed form. [br][br]This applet allows you to explore the decomposition [br]of integers into sums of multiples of powers of various bases.[br][br]Is the decomposition of a given number unique? If yes, how do you know? [br][br]If no, how many different decompositions can you find for a given number?[br][br]Can you devise a way to write fractions between 0 and 1 in different number bases ?[br][br][color=#ff0000][i][b]What problems could/would you set for your students based on this applet ?[/b][/i][/color]
