ملخص الدرس

This lesson introduces intervals as a way to represent subsets of real numbers. It covers bounded intervals (closed, open, half-open) and unbounded intervals, and how to represent them on a number line. The lesson also explains operations on intervals, including intersection, union, difference, and complement, using both number lines and set notation.

هتتعلم إيه فى الدرس ده

• Intervals are subsets of real numbers that can be bounded or unbounded.
• Bounded intervals include closed [a,b], open (a,b), and half-open (a,b] or [a,b).
• Unbounded intervals extend to positive or negative infinity.
• Operations on intervals (intersection, union, difference, complement) follow the same rules as set operations.
