It's my turn to blog today

Class Agenda:

I) Bell Ringer
II) Math Language
III) Exponential Notation
IV) Factors of Natural Numbers

Notes:

Today in class we reviewed prime factorization. We learned that using this technique, math can be much easier. Here are some examples on prime factorization:

8 > 2*4 > 2*2 ....therefore you get 2 cubed

148 > 2*74 > 2*37 ....therefore you get 2 squared times 37

*sorry if thats not clear, i cant show it well with typing*

We learned that a technique that can be used to make solving equations without a calculator easier.
Example:

(35*23*72 )/(32*2*7)
This can be simplified to 33*22*7 by subtracting the exponent from the numerators to the similar numbers in the denominator "35 and 32, 5-3=2...so you get 33"

We also review adding evens and odds added in a certain combination, even plus even, odd plus odd, or odd plus even, will always become either an even or an odd
Example:
Odd+Odd= Even
Even+Even=Even
Odd+Even=Odd

Also we learned that any even can be written as 2x, and that any odd can be written as 2x+1

Homework:

Page 26 numbers 2, 3, and 7

*RANDOM TIP*
Paying attention in class and taking notes will benefit you, not doing so may cause you to have trouble

QUESTION:
Are there any shortcuts to prime factorization?????

  1. Umm... No only if you start to divide by 2 then so forth....

  2. there is no shortcut to prime factorization.

  3. I don't think that there really is a shortcut to prime factorization... but there could be more understandable ways to do it, like by branching the factors out.

  4. it's not possible, i don't think it can be easier as it is already

  5. No i don't think there's a shortcut to prime factorization. I wish there was.

  6. Prime factorization is fun, it's pretty simple, who needs a shortcut!

  7. there probably is an easier way but we dont know about it yet.so until this point there is no easier way.

  8. I believe this lesson we learned today wasn't as difficult as i would of expected to be and i actually knew what i was doing :)

  9. prime factorization is already pretty simple..i doubt theres a short cut

  10. I enjoyed this subject as much as my classmates did, as it was easy an fun. But I do have a shortcut that will help you learn this right away. First, pay attention to the teacher. Second, take notes. And finally, do your homework. Those are the only shortcuts that will help you become a master of mathematics :P

  11. i dont think that theres a short cut for prime factorization, there really easy to if you start dividing by two and getting some more practice maybe will help you to get better at it.

  12. there is no shortvut to prime factorization but an easy and organizede way to complete this would be to use the branches.
