Cost of Production
This lesson covers the concept of cost in economics, focusing on the cost of production. It explains different types of costs, such as fixed and variable costs, and discusses the factors of production that contribute to overall costs.
- 12:54 “So this is how you draw the graph, it's very simple, first cost is set to be worth, it's set to be horizontal to the x-axis, are we together, it's not more than that, okay? Then let's move to the next one, please, and th...”
- 16:04 “you calculate your worth, your total cost, please take note, your total cost here is going to be worth, it's going to be fixed cost, plus worth, plus variable cost, okay, remember the first one I get to you is worth, is...”
- 14:26 “to incur more costs for it to get a better worth service, than the cost of where as well. The cost of field is another good example of worth of a variable cost, and your variable cost, what is the graph, look at the boar...”
Simplification of Algebraic Expressions
This lesson covers the definition of algebraic expressions and their components, including terms and coefficients. It explains how to identify like terms, perform arithmetic operations on similar terms, and simplify expressions by inserting or removing brackets.
- 08:01 “But now we are talking about constants and coefficients. What is a constant? What is a coefficient? In this expression, five is a constant. How is it a constant? Because it does not change its value. It continues to be f...”
- 01:36 “Here we deal with alphabets majorly, such as X or Y to represent the unknown values. Here are some examples of algebraic expressions. We have two X plus 10 Y plus one. You can note that it does not have an equal sign. Wh...”
- 11:12 “How many terms do we have here? We have one, two, three, four. Why do we have y as part of the terms? Because, of course, we have an invisible one here. So it doesn't stand on its own. Remember, I told you a term can jus...”
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.
- 00:47 “as representations of numbers where the value may vary. For example, you get 500 NARA Pokemon every month, and you know that for that month, what you do with it is you spend it on sweets, transports, and data for your mo...”
- 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.”
- 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...”
