What does expanding a number really mean? When we expand a number, we are showing the value of each digit in that number. For example, the number 521 has a total of 500 + 20 + 1. This number has been written in its expanded form by showing the value of each digit.
In the case of a decimal number above 32.043, we will write each number according to its place value. This will be done by multiplying each digit by its place value and then adding them together. In this case, 32.043 in its expanded form will be;
(3×10) + (2×1) + (0× 1/1000) + (4×1/100) + (3×1/10)
(30)+ (2) + (0.0) + (0.04) + (0.003)
