Math
In Math I learn many things and I got many formulas. Such as:
- Fn = 2 + 3(n-1) = 2 + 3n - 3= 3n - 1
- Fn = 6 + 2(n-1) = 6 + 2n - 2= 2n + 4
*Number Sequences
- 1, 4, 7, 10, 13....
16, 19, 22
- 8, 5, 2
-1 , -4, -7
- 7, 20, 33, 46
59, 72, 85
*Index Notation vc. Expended form
- Expended = 2 x 2 x 2 x 2 x 3 = 48 ----> Index= 2(4x) x 3 = 8
*Prime Factorization
88 = 11 x 8 = 2 x 4 = 2 x 2= [2 x 2 x 2 x 11 = 2(3x) x 11]
*GCF & LCM
18 = 2 x 9 = 3 x 3 [2 x 3 x 3 x 3]
27 = 3 x 9 = 3 x 3 [3 x 3x 3]
GCF= 3 x 3 = 9
LCM= 3 x 3 x 3 x 2 = 54
*Ascending and Descending Order
Ascend = 1, 2, 3
Descend = 3, 2, 1
*Adding & Subtracting Integers
- 5 + 7 = 12
- 5 + -7 = 5 - 7 = -2
- 5 - -7 = -2
- -5 + -7 = -12
*Order of Operations
(2(3x)) x 2) + 2 : 2 ----> (8 x 2) + 2 : 2 ----> 16 + 2 : 2 ---> 16 + 1 = 17
- Fn = 2 + 3(n-1) = 2 + 3n - 3= 3n - 1
- Fn = 6 + 2(n-1) = 6 + 2n - 2= 2n + 4

Reflection
For me, math is the hardest subject. Because its hard for me, so I should study more for math. Especially "Fibonacci", I don;t really understand about it. The main thing ti improve my math skill only I should study more and memorize the way of doing the problem and the formula.
