Assignment 1.1 – Place Values of Whole Numbers
Numbers are written using the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. The placement of these digits in any number, determines the meaning and value of the number.
In the numbers 597 and 851, the 5 looks the same (face value) but the place value is different.
597 – the 5 in this number means that we have 5 hundreds
851 – the 5 in this number means we have 5 tens
The value of each digit of a number written in standard form can be expressed when we write the number in expanded form.
The number 834 576 expressed in various forms is as follows:
Standard Form:
834 576
Expanded Form:
(8 x 100 000) + (3 x 10 000) + (4 x 1000) + (5 x 100) + (7 x 10) + (6 x 1)
