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 that __its goin__ to be __a__ introduction to the number´s theory.
 * Great Job ! !** 4pts

Mention five words you think you might listen to in the video. Numbers,sets,divisibility,Euler,aplications.

1. Mr. Mc Call is solving three types of equations in this video. Which are those types of equations? -Equations with one variable. -Equations with variable **s** on both side. -Formulas.

2. What are the two keys he mentions for solving any equation? -Adding the inverse. -Use the reciproc **al** of a number.

3. a. Mention the steps he takes to solve the 1st problem. -He added the inverse of __minues__ two in the left side. -Then he __multiply__ by the reciproc of -1/5

b. What kind of equation is this one? Equation with one variable

4. a. Mention the steps he takes to solve the 2nd problem. -First he uses the distribute propertie **s** on the left side. -Then he adds the inverse of 4x. -Then he adds the inverse of -2. -Finally he multipl__y__s by the __reciproc__ of 5.

b. What kind of equation is this one? -Equation with variable **s** on both side.

5. a. Mention the steps he takes to solve the 3rd problem. -First he adds the inverse of 2l. -Then he divide **s** all the terms by 2.

b. What kind of equation is this one? -Formula equations.

6. a. Mention the steps he takes to solve the 4th problem. -First he multiplys be the inverse of 1/5. -Then he adds the inverse of c.

b. What kind of equation is this one? -Formula equations.

c. What’s the difference between problem 3 and problem 4? The variable in the second problem is divided by a constant.

7. Did you like the video? Yea, the video is nicely done and the explanations are clear.

8. What new things did you learn? Nothing really, since __this are__ things that __i__ already knew and __i__ use them everyday.
