Video+3

Super... 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? I think it will be about basic (binary) operations on real numbers, and perhaps about solving first degree equations.

Mention five words you think you might listen to in the video. Number Algebra Sum Equation Equals

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 with a variable in one side of the equation with a fraction. Equations with a variable on both sides of the equation. Equations with multiple variables (solving it for one).

2. What are the two keys he mentions for solving any equation? Fist the additive inverse (a number added to its inverse additive equals 0) and the multiplicative inverse (a number multiplied by its inverse additive equals 1)

3. a. Mention the steps he takes to solve the 1st problem. 1. He first finds the variable 2. Then he gets rid of the -2 (by adding a +2 to the LHS of the equation) 3. Then he adds a 1 multiplying x (x*1=x) 4. Then he gets rid of the -1/5 (by multiplying by -5 on the LHS of the equation)

b. What kind of equation is this one? An equation with a variable in one side and a fraction.

4. a. Mention the steps he takes to solve the 2nd problem. 1. He first multiplies the RHS using the distributive property ( a(b+c)=ab+ac) 2. Then he adds all the terms with an x on the LHS (distributive the other way around) 3. He gets rid of the 4x on the RHS (by adding -4x on the LHS) and uses the distributive property like he did on step 2 to get 5x 4. Then he gets rid of the -2 ( by adding +2 on the RHS) 5. Finally he gets rid of the 5 (by multiplying 1/5 on the LHS)

b. What kind of equation is this one? One with a variable on both sides.

5. a. Mention the steps he takes to solve the 3rd problem. 1. First he identifies the variable that he wants to find the solution 2. The he gets rid of the 2L (by adding -2L to the LHS) 3. Finally he gets rid of the 2 (by dividing the LHS by 2)

b. What kind of equation is this one? It’s an equation with multiple variables.

6. a. Mention the steps he takes to solve the 4th problem. 1. First he identifies the variable he wants to find the solution for 2. Then he gets rid of the 1/d (by multiplying d to the LHS) 3. Finally he gets rid of the c (by adding –c to the LHS)

b. What kind of equation is this one? It’s an equation with multiple variables and a fraction.

c. What’s the difference between problem 3 and problem 4? In the 4th problem there’s a fraction and on the 3rd problem we need to use the distributive property.

7. Did you like the video? It’s a nice video for those who are beginning to solve first grade rational equations.

8. What new things did you learn? I learned that the inverse multiplicative is also called the reciprocal of the number.
