the areas of how numbers are arranged and what digits are present in a number.<\/p>\n\n\n\n<p>The Generalised Form is a way to represent a number as a collection of its digits multiplied by their associated place value to give students a better understanding of how a number is built up by groups of ten (units), hundredths (tens), thousands (hundreds) and so on.<\/p>\n\n\n\n<p>For example, 39 can be expressed as the sum of 30 (10 x 3) plus 9 representing the digit 3 as being &#8216;in the tens place&#8217; and the digit 9 everything.<\/p>\n\n\n\n<p>If you are learning place value concepts
