1.2.2 Shifting digitsHave you thought what fun it would be if the digits in a number could shift(move) from one place to the other?Think about what would happen to 182. It could become as large as 821and as small as 128. Try this with 391 as well.Now think about this. Take any 3-digit number and exchange the digit atthe hundreds place with the digit at the ones place.(a) Is the new number greater than the former one?(b) Is the new number smaller than the former number?Write the numbers formed in both ascending and descending order.Before795Exchanging the 1st and the 3rd tiles.After59 97.If you exchange the 1st and the 3rd tiles (i.e. digits), in which case does thenumber become greater? In which case does it become smaller?Try this with a 4-digit number.h.ly |
