Here we go!
We are going to move further into equations, once you have a firm basis in this we can move on.
This is very critical to learn as we will need it when we begin graphing ::GASP::

Its time to step it up, please continue emailing (personal email) me any questions and I will continue clarifying further. We have a very good discussion going and it will get more complicated as we continue.

Bane
We need one more concept before we get back into algebra.
The following is what many students believe is the bane of their mathematical existence, this is what gave students nightmares before algebra: Lowest common multiple!
Round 1: Fight!

Chinese contribution
200 B.C.E
Diogenes Laertius (c. 200)
Liu Hong (fl. 178-187)
Wang Fan (217-257)
Diophantus of Alexandria (c. 250?)
Sun Zi (c. 250?)
Zhao Shuang (Jun Qing) (c. 260)
Liu Hui (c. 263)
Porphyry (c. 234-c. 305) (Malchus the Tyrian, Porphyrius)
Anatolius of Alexandria (fl. c. 269)
Sporus (c. 280)
Iamblichus (c. 250-c. 350)
Xiahou Yang (c. 350?)
This is a golden era for the Chinese and although they wont make such large contributions as this in the future (so far) it marks a beginning where the Chinese never let up on their contributions to not only math, but science as well.
In fact, recent studies have shown a large part of scientifically peer reviewed papers being published now are actually Chinese.
http://articles.cnn.com/2011-03-29/world/china.world.science_1_china-output-papers?_s=PM:WORLD
The article mentions how the US is still ahead, but that it may be reaching an apex. This is the price the US will pay for having a large portion of its populance remember the roster of their favorite sports teams or the cast of their favorite TV shows rather than the names and the contributions of great people.

Timeline Update
100 C.E.
Balbus (fl. c. 100)
Menelaus of Alexandria (c. 100 CE)
Nicomachus of Gerasa (c. 100)
Zhang Heng (78-139)
Theon of Smyrna (c. 125)
Ptolemy (Claudius Ptolemaeus) (c. 100-c. 170)
Marinus of Tyre (c. 150)
Nehemiah (c. 150)
Apuleius of Madaura (Lucius Apuleius) (c. 124-c. 170)
You may have noticed I am using B.C.E. and C.E, as in Before Common Era and Common Era
While its not new, its much more popular now.
Its good to move away from religion based historical periods, now while this change may indirectly still be linked to christianity its a step in the right direction.
