Start date Mar 25, 2013

In summary, the notation [7,8) represents a range of numbers from 7 to 8, including 7 but not including 8. The use of a bracket and parenthesis indicates whether the number is included or excluded from the range. This notation can be read as "from 7 to 8, including 7 but not including 8". It is commonly used in mathematics to represent intervals or ranges of numbers, including decimals and fractions. It is particularly useful when dealing with inequalities.

1. What does the notation [7,8) mean?

The notation [7,8) is a way of representing a range of numbers. The bracket on the left side, [7, indicates that the range includes the number 7. The parenthesis on the right side, 8), indicates that the range does not include the number 8.

2. Why is there a bracket on one side and a parenthesis on the other?

The use of a bracket and parenthesis in this notation is to indicate whether the number on that side is included or excluded from the range. A bracket means the number is included, while a parenthesis means the number is excluded.

3. How do I read the notation [7,8)?

The notation [7,8) can be read as "from 7 to 8, including 7 but not including 8". This means that any number between 7 and 8, including 7 but not including 8, is part of this range.

4. Can the numbers in a range be decimals or fractions?

Yes, the numbers in a range can be decimals or fractions. For example, [1.5, 2.5) would represent a range from 1.5 to 2.5, including 1.5 but not including 2.5.

5. How is this notation used in mathematics?

This notation is commonly used in mathematics to represent intervals or ranges of numbers. It is especially useful when dealing with inequalities, where a number may be greater than or less than another number, but not equal to it.
