Factorization of Algebraic Expressions
This lesson covers the factorization of simple algebraic expressions and quadratic expressions. It includes methods for identifying factors and solving related word problems.
- 07:51 “Let's trace it out. What would be the possible common factors between these things? The possible common factors that can pick up, pick out themselves. Looking at it carefully, what do we have? We have 3, top up, a 3. We...”
- 26:04 “It would be twice the number of girls, so that would be 120 times two. So, 120 times two, that would give us 240. So, when you had 240 plus 120, it would give you 360, total number of students in the school. What problem...”
- 08:37 “A multiplied by, what do we have b? So if we take it out, we're going to be having 3, a, b. Now, 3, a, b, 3, a, b, 3, a, b becomes much of a common. But wait, 3, a, b is common to the both sides. But that now, the final...”
Similar Shapes
This lesson covers the identification of similar shapes such as triangles, rectangles, squares, cubes, and cuboids. It explains the criteria for similarity, including proportional sides and equal angles. The lesson also includes methods for enlarging figures using scale factors and calculating lengt
- 30:51 “So what do we have? K multiplied by... What is the old one that you have? You have 1.5. It is the old one. The old one is given to be 1.5. 1.5. So remember, we have gotten our K. What is our K? Our K has already been arr...”
- 25:22 “these 2, if it cannot be in this form then your answer is wrong, now the last part is applying it to water problem, how do we apply it to water problem, how using your scalar factor to solve a problem, olatical wants to...”
- 32:36 “Calculate the area of one phase of cube K, area that is the area of the cube. Then calculate the volume of cube K. You calculate the volume of cube K. Thank you very much, I come to the end of the class. My name is Oyase...”
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.
- 18:13 “That's 10 times 10. 10 in two forms. That's 10 times 10. 10 in two form. 10 times 10. 10 times 10. Now, going forward, we have that gives categorically equal to 3.14.1.6 divided by 10 times 10 is 100. 100. So, we have 3....”
- 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...”
- 19:01 “Now, with these two examples, we will give you an idea to what pi equation or pi really means. Now, you have some questions, which I expect you to do. You have said calculate 16 divided by 9 in 3 decimal places. 16 divid...”
Translating Word Problems into Equations
The lesson teaches how to translate word sentences into mathematical equations. It covers the use of variables to represent numbers and how to express word problems as algebraic expressions. Students will learn to solve simple equations and check their answers.
- 12:56 “The sum of three consecutive numbers is 11. Remember when we talk about consecutive numbers, that is, say, this is example 4. I want to start with 4. First, let's do 4. Now, sum of three consecutive numbers is 11. So thr...”
- 02:23 “sweets you have data and then you spend it on transport. So you can easily represent this with Z, represent this with D and represent this with S. So for your 500 NARA, this is, to know how much is left every month, say...”
- 19:25 “We've come to the end of today's class. Thank you so much for watching. My name is Dorkas Aoye, till next time.”
Measures of Central Tendency
This lesson covers the measures of central tendency, including mean, median, and mode. Students will learn how to calculate these measures using given data sets. The lesson also explains how to handle data with and without frequency.
- 17:36 “cumulative frequency. So whenever we have a cumulative frequency in the table, such table is called cumulative frequency table. When we don't have a cumulative frequency table, it is only just a class and a frequency. We...”
- 18:25 “And the formula also get i is Q i equals l plus n i all over 4 minus CF all over F times C. And the total code type we have to find is 3. Our high is 3. So it means wherever you see i, we are putting 3. So we have it mea...”
- 04:01 “three occured two times. So we can have, our Mood can be, can be words two and three. So we can have more than two Mood in a set of data. [BLANK_AUDIO] Now let's look at example number one. [BLANK_AUDIO] Calculate the ma...”
