Introduction to Sets
This lesson defines a set and explains set notation. It covers types of sets, cardinality, and set operations. Venn diagrams are also introduced for solving real-life problems.
- 02:33 “from the multiples of four up to 40. So we have four eight twelve sixteen twenty twenty four twenty thirty two thirty six and forty. And also, let's also define the cardinality of the sets. When we say that it said, it s...”
- 01:43 “a, f, and m. A defines the set to be odd numbers from one to 21 and f defines the factors of 30 and hem defines multiples of four from up to 40. So we have the sets A, which is the set of odd numbers from one to 21. So w...”
- 03:22 “the number of elements in the set A is three. Example number one, given that the universal sets equals all the days of the week B sets equals all the days of the week whose letters begins with S. And we have to list all...”
Counting in Binary
This lesson teaches how to count using the binary system, which uses only the digits zero and one. Students will learn to represent numbers in base two and understand the place values associated with binary digits. Activities include grouping counters to illustrate binary numbers.
- 02:33 “We use this paper abacost to improvise. I don't know if you've seen an abacost in real life. We have 8, fours, twos, then units. Okay, then we have one here, nothing here, one here, one here. I would like us to do this t...”
- 04:52 “One, two, three, then four. Then I have one left. Okay, let's continue the activity. Then next one now is to group them in eight, four, two, and units. Okay, let's see, let's do that now. We've grouped this into, now let...”
- 09:39 “So yeah, there's nothing here too. Okay, yes, two, we have two. So I write one for two. So this two is now gone. We don't have nothing left. So nothing here. So for our base, for our ten, the equivalent in base two is on...”
