Letters can be arranged in different ways to create words with different meanings. For example, WAS and SAW use the same three letters, but since the letters are in different places in each word, the words have different meanings.
Similarly, the digits 1, 2, 3, 4, 5, 6, 7, 8, and 9 can be arranged in different ways to create numbers with different values. The value of each digit depends on its position in the number.
In this module, you will learn and practice the following skills:
- Understand the relationship between a digit’s position in a number and its value.
- Compare the values of digits in different places.
- Multiply and divide numbers by powers of 10 and explain the result.
