## Math Online News

AUGUST 6th, 2018: Math Online just reached 3000 pages of content :D! |

JULY 30th, 2018: The Abstract Algebra section is undergoing clean up. A bunch of pages have been reorganized and/or modernized! Additional topics have also been added. |

MAY 3rd, 2018: The Topology section will be undergoing some cleaning up for the next couple of weeks. |

JANUARY 8th, 2017: Happy New Years! Tons of additional math pages will be added this year! |

JANUARY 10th, 2016: The Number Theory section is almost fully overhauled! About 80% of the pages have been cleaned up with various additions/removals, improved wording and notation, etc… |

DECEMBER 28th, 2015: The colours of the hub pages have been modified. |

NOVEMBER 10th, 2015: I've modified the hub page links to be more colourful! |

SEPTEMBER 28th, 2015: Math Online now has over 1500 pages of content! Woo :)! |

SEPTEMBER 2ND, 2015: Just changed the Math Online favicon to a modern and sleek $*$ operation symbol! |

SEPTEMBER 1ST, 2015: Lots of updates! All of the hub pages (except for Number Theory) are condensed to reduce vertical scrolling. A lot of the main graphics have also changed including the icons representing Linear Algebra and Graph Theory. Incorrectly sized headings on hub pages have also been fixed! |

AUGUST 28TH, 2015: The "Abstract Algebra" section was created a few days ago and the front page has received some aesthetic changes including colour-coded hub pages. The background also changes upon refresh! The Number Theory section will also be getting some edits over the next week as most of the Number Theory pages are low quality in comparison with the rest of the site. |

AUGUST 17TH, 2015: Over the last 9 days I have worked extensively on the new, Combinatorics page! For the following week I will be finally working on neatening the Graph Theory pages, adding more pages to the combinatorics section, and perhaps starting on a new section or working on an existing section. |

APRIL 4TH, 2015: Math Online officially has over 1000 pages of content available! Can't wait for the next 1000 pages of content! |

MARCH 11TH, 2015: I have cleaned up the Differential Equations page and made it more user friendly. I have also done a little cleaning on the Linear Algebra pages. I plan to update the Graph Theory and Number Theory pages in May as their styles are a little outdated with the new standards that have been in place on the site. I have also added a new search feature on the main page of the site! |
