Rational and Non-Rational Numbers
This lesson covers the identification of rational and non-rational numbers. It explains the characteristics of different number sets, including natural numbers, whole numbers, and integers. The lesson also discusses the significance of the number PI in relation to circles.
- 00:56 “And to determine particle appropriate values for the PI, the PI. Now, the PI is usually used doing what? A cycle, that's the cycle phase of the cycle, to bring in your PI. How do we determine that? Now, move on straight...”
- 01:42 “They're natural numbers. They include the positive counting numbers. So you talk about your 1, your 2, your 3, your 4, your 5. As far as this is positive and this is counting number, it is called a natural number. Take n...”
- 00:10 “Hello, I'm Oyase Sunday, and I'm taking Matamatics JSS 3 class. We're treating an interesting topic for today. And the topic is rational and non-rational numbers. We're taking it from the numbers and numerations. Now wha...”
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.
- 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...”
- 00:11 “Hello everyone, I am your Mathematics teacher, Esther Oluchi Ibebukwe. Today, our topic is counting in base two. By the end of this lesson, you should be able to count in group of two's. Number basis, a number base is th...”
- 04:06 “For example, let me use stick like maybe a stick. Let's count out nine. I want to do this together. You can do that on your own end. Three, four, five, six, seven, eight, nine. These are nine counters. Now we have to gro...”
Addition of Binary Numbers
This lesson teaches how to add two or three-digit binary numbers. It covers the basic rules of binary addition, including carrying over when the sum exceeds one. Several examples are provided to illustrate the process.
- 02:30 “one, zero, one, one, one, one, one, so we have one, zero, one, one, one, one, one, one, one, one plus one is one and zero plus one, this, right one, take one to the next column, one plus one is what, ten, that's one and...”
- 01:37 “give you one and zero. Write this one, then take the other one, carry the other one to the other side of the next column, one plus one, we give you ten, sixty, one and zero, the right one, then take one to the next colum...”
- 03:15 “So we have, we have done this one plus one, this is one and zero, plus one, this, plus one. How do you do this? One plus one is ten already, then take one here, one plus one and under what, another ten. So we have it on...”
