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...”
- 17:33 “let's say we have the number of A, don't forget we said the cardinality of A says can be represented by this. So we have 23 and we have the number of B to be 12 and we have the number of A union B to be 35 and don't forg...”
- 15:58 “So let's say we have what is the reason between these two? We use what we call a cardinality of a set to do that. A or B, that is equals the number of A plus the number of B. Then we have minus n the number of this. Or w...”
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.
- 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...”
- 07:59 “Let me convert it to base two for better understanding. So let's go. We have ten in base ten. So let's represent the powers of two on our paper abacus. So we have we have the eights, fours, twos, then units, which is onc...”
- 01:45 “Now, counting in groups of two. Counting in group of two is also known as a binary base system. A binary number is made up of zero and one, like I said earlier. An example is one, zero, one, one in base two. One, zero, o...”
