I. Before you watch the video answer the following questions. The title of the video is "Algebra I" What do you think this video will be about? This video talks about the number theory and elementary algebra. Mention five words you think you might listen to in the video. Numbers, divisibility, relation, theory, Euler. II. Now click on the following link and watch the video. While watching, please answer the following questions:  []

1. Mr. Mc Call is solving three types of equations in this video. Which are those types of equations? Equations of one variable, equations of variables on two sides and equations with multiple variables. 2. What are the two keys he mentions for solving any equation? Find the opposite number and the inverse number. 3. a. Mention the steps he takes to solve the 1st problem. Identifies the variable, add two to both sides, multiply by minus five on both sides. b. What kind of equation is this one? This is of one variable. 4. a. Mention the steps he takes to solve the 2nd problem. Identifies the variables, parentheses resolves, are grouped the variables of the one side, add two to both sides and simplifies. b. What kind of equation is this one? Equations of variables on two sides. 5. a. Mention the steps he takes to solve the 3rd problem. Select a variable to solve, subtracted 2l on both sides, multiply by 1/2 on both sides. b. What kind of equation is this one? Equations with multiple variables. 6. a. Mention the steps he takes to solve the 4th problem. Select a variable to solve, multiply by d on both sides and add minus c on both sides. b. What kind of equation is this one? Equations with multiple variables. c. What’s the difference between problem 3 and problem 4? The form of the equation. 7. Did you like the video? Yes, is ok.

8. What new things did you learn? That math is quite easy.
