1.1 Positive numbers and place value

Described image
Figure 1 Place value

Let’s look at positive numbers in more detail.

The place value of a digit in a number depends on its position or place in the number:

The value of 8 in 58 is 8 units.

The value of 3 in 34 is 3 tens.

The value of 4 in 435 is 4 hundreds.

The value of 6 in 6 758 is 6 thousands.

Look at the following example, which shows the place value of each digit in a seven-digit number.

Activity 1: Working with place value

  1. Here are the results of an election to be school governor at Hawthorn School:

    • John Smith: 436 votes
    • Sonia Cedar: 723 votes
    • Pat Kane: 156 votes
    • Anjali Seedher: 72 votes

    Who won the election?

Answer

The person who wins the election is the person who gets the most votes.

To find the biggest number we need to compare the value of the first digit in each number. If this is the same for any of the numbers, then we need to go on to compare the value of the second digit in each number and so on.

  • The value of the first digit in 436 is 4 hundreds.
  • The value of the first digit in 723 is 7 hundreds.
  • The value of the first digit in 156 is 1 hundred.
  • The value of the first digit in 72 is 7 tens.

Comparing the values of the first digit in each number tells us that the biggest number is 723, so Sonia Cedar is the winner of the election.
