This week in math I learned/understood how to substitute. Last year we learned the concept but I never really understood how to do it. With substitution we must isolate one variable, probably the easiest one to isolate. From there we… Continue Reading →

This week we learned a technique/acronym to factor polynomial expressions CDPEU Can Divers Pee Easily Underwater Common Factor, Difference of squares, Pattern, Easy, Ugly C – Check if there is a common factor D – Check if there is a difference of… Continue Reading →

  This week our subject was on trigonometry and more specifically this day was focused on finding the missing angles of a right angle (90 Degree) triangle. This missing angle was called “Theta” and could be found using SOH CAH… Continue Reading →

This week I learned that a cone is 1/3 of a cylinder or how a pyramid is 1/3 a cube, I also learned about slant height and how it is involved with pyramids and cones. To find the slant height… Continue Reading →

This week I learned about integral exponents, and how to convert negative exponents to positive exponents. The general rule for exponents is, = =  Exponents have a pattern of being divisible by the base so continuing to the negative, you… Continue Reading →

This week I learned and practiced about how to convert units from different levels of measurement (e.g meter, centimeter, millimeter), and that converting from a smaller unit to a larger unit will equate to a smaller answer, while converting from… Continue Reading →

This week in exponents I learned a more simple technique for converting between a fraction exponent and a radical. Ms. Pahlevanlu calls this technique “flower power” and it is an easier way to recognize/remember which numbers go where. Why it… Continue Reading →
