2: Math Cartoon! Text of Cartoon: Tom: Jerry is running 70 miles per hour at a constant rate and he is one mile away from me. I'll need to sprint for at least 71 miles per hour at a constant rate to catch him in 1 hour. Jerry: I'm so adorable Tom will never catch me! ~Distance between Tom and Jerry: 1 mile~

3: Discovering a New Earth 430 Light Years away from Earth On April 1, 2008 Astronomers found and analyzed infrared images of a new star and planet. The telescope that found this new place is the Spitzer Telescope. The star was around 10 to 16 million years old. The dust cloud suggests that it may one become a rocky planet like earth that may one day be able to support life. Though this planet may be like earth, it will take millions of years to form. This new Earth-Like planet is said to be 430 light years- 2.5X1015. This new earth-like planet is surrounded by a dust cloud that is bigger than our asteroid belt and can easily create a new planet. This planet is forming at about the same distance from the sun as Earth. Scientists also analyzed that the new planet has some of the same materials that Earth is made up of. This planet also has an ice belt that suggests that it will have water on it.

4: Pythagoras Written by: Patrick Shea Austin, TX- Pythagoras was born in the year 582 BC in Samos, Greece, and lived a life that greatly involved math. He had two brothers and a sister. He was well educated from an early age, learning to play the lyre, recite poems, and read Homer. He made a school on Samos called the “Pythagorean Semicircle” and he taught everyone who came to him. Three philosophers influenced Pythagoras as he was young, but the most important was Pherekydes, who was his teacher. Pythagoras soon became very interested in mathematics and astronomy so he traveled to Egypt to learn more about them.

5: Later, Pythagoras started his own cult of people that called themselves the Pythagoreans, and his cult was based on religious, political, and philosophical beliefs. They believed in incarnation and Pythagoras thought of himself as a Trojan warrior in a past life. Pythagoras had many discoveries in math such as the first person to discover the existence of irrational numbers. He also found the Pythagorean Theorem, which stated that on right triangles, A2 + B 2 = C2. He was also the first to distinguish between prime and composite numbers. He also found an equation for 3D boxes that was D2 = H2 + A2 + B2. Pythagoras went back to Samos and died around 520 BC.

6: A Math Career By Frankie Chen Ever want to build your own robot? If you do, you had better be good with mathematics. Why? The reason is that without good mathematics in your Robotics career, you'd fail to meet the bare minimum of being a robotics engineer. Programming is key if you want to become successful in this career, and knowing how to calculate the directions for your robot will be needed in programming. The directions would be complicated so when you start programming the robot, you have to put in the exact and correct degree it needs, and quickly estimate the time it would take for your robot to cross and certain path. Another point in programming where math is needed is to program the sensors as you'll have to, again, estimate how dark an object has to be for your robot to react. Next you might also want to calculate how much you can put in a robot and still not go over its memory. Another way where you'd need math skills is when you need to have actually build the robot. A sense of planning, strengthened from math, would help here greatly. This is a few

7: of the many reasons that mathematics will help you greatly in robotics engineering, and in nearly all other careers. A good sense of math always helps.

8: Word Problem of the Week | Bob works at PlayMath's Magazines. He earns x amount of money everyday by working for 3 hours a day. By the end of the fourth week of his job he earned 253 dollars. If Bob keeps earning money at the same rate, approximately how much money will he have earned the end of the sixteenth week? Answer: \$1,008
