How to make a mathcast!

First pick a problem a math problem that you are going to solve. Then, make a twitter account because that is where you are going to publish your mathcasts. Also, screenr uses your twiter username. Next, go to screenr.com and make an account. Then you open the paint icon on your computer and you write your problem. Then, go back to screenr and adjust your recording screen so it just shows the paint screen with your problem written on it. Then you press record. You talk into the headset/microphone as you are solving your problem. You say what you are writing. When you are finished, you press the stop button and you have to title your screencast. You are going to title it with your name, chapter, your problem and then a hashtag so someone else can find it. Then you can tweet it on twitter.

Mathcasts!

I like mathcasts because they are an easier way to learn. Since people learn at different speeds, with mathcasts you can stop rewind or rewatch a lesson if you are having trouble. Also, if you are learning it quickly you can skip and go ahead.

Real World Parabolas

Scattered Data Post

here Link to original form.
First I asked 2 questions.
Link to Results Spreadsheet

Then I graphed those 2 questions

Then I graphed it on graph paper.








Then I drew the line of best fit.










I chose to points on the graph and used the slope formula to find the the slope and then I used that to find the y-intercept. That gave me the formula of the line of best fit, y=mx+b.






Then, i put all the points into a Graphing Calculator.

Then, I found the Calculators line of best fit.








I did that by finding the calculator's version of the slope and the y=intercept.

Then, I entered the exact number into the y=. If you don"t enter the exact number, the equation could be off.








Then, I finally graphed the line of fit.







I asked how many sports everyone played and what is the actual day of their birthday? There was a positive correlation between the two questions. My written equation was y=x+4 and my Graphing Calculator's equation was y=1.606646+10.60403727. The two slopes were pretty close to each other but the y-intercept was around 6 numbers apart. The question that could be answered by the equation of best fit is the relationship between the number of sports you play and your birthday.

Adding and subtracting Integers

Adding and Subtraction Integers

A) 5+ -8 Since it is a positive 5 and a negative 8, you subtract 5 from 8 but since the negative number is greater the the positive number, the answer is negative which is -3.

B) -4+10 Since there is a negative 4 and a positive 10 you subtract 4 from 10 but since the positive number is greater then the negative number, the answer is positive which is 6

C)4-9 Since they are both positive you just subtract 9 from 4 which gives you a negative number. The answer is negative because the greater number is being subtracted from the littler number.

D)-8-(-9) Since they are both negative numbers, you add them together getting a negative number. You add them together because when you add numbers to a negative number, it get smaller. The answer is -17.
