    I changed font colour so you need to highlight to read it (hopefully), slightly better? It's still a bit visible but I dunno code for background and my colour blindness made it hard to work out what there was too much colour of :P

    That's not one on the list is it/it's more of a custom colour right, 'cause I haven't ever seen it on that. xD

    Eum we're off maths topic so D:

    I have 7 bananas and 5 camels and the camels all eat half a banana how many bananas do I now have D:

    Thrivvy you were making your maths right xD Or is Decus making the next ones/your thing before was just hypothetical?

    You may thank Thrivelia for the first problems of the new year!I edited them a bit so they weren't as hard to read :3 Enjoy!

    Ena.

    Waffy is an avid animal keeper.. collector? Nothing will stop him from collecting those animals even if they belong to someone else D8 .

    He goes to the Dynasty Mansion with only 2 cats and 3 dogs with him. In the mansion he takes all 23 of Synta's cats, 13 of Synta's dogs, and 3 of his British goldfish. He sees Decus and takes 14 of his cats, 6 of his dogs, a dozen of his 14 hamsters, 3 of his lizards, and 4 of his mice. He also sees Miiko and takes only 3 of her 4 meeses, half of her 8 polar bears, and 17 of her sharks. Waffy leaves the mansion with his .. expanded collection..

    How many animals does Waffy have now?

    Dva.

    Decus is having a cookie party. Decus bakes 43 cookies for all the guest. Kis, Waffy, Synta, and a bunch of other Dyna people come. Waffy decides to help decus with the.. food.. . Waffy bakes 3 cookies to bring to the party. (He only had.. not even half of the Pillsbury cookie dough roll thing. This dough from 23 years ago. It's from the last time he baked cookies... for his.. special someone). Miiko comes and takes 3 and a quarter of a cookie. Synta comes and takes 14 and the rest of the cookie that miiko took. Kis takes 5 cookies. Hea takes 1. EX takes 3. Teri takes 4. Waffy comes and takes 4 (he want's to profit from this!!!).

    How many cookies does Decus have left?

    Tri.

    Synta is buying watermelons for a ... family.. reunition. He plans to buy 34 watermelons so each person gets two (one for lunch and one for dinner) . Each watermelon weighs 50 kg. 1 lb of watermelon costs $0.17, but if you buy more than a dozen watermelons, the ones after the dozen will cost you $0.16/kg.

    How much does Synta pay for the watermelons? :D
    1) Waffy now has 105 animals with him :D

    2) Decus has 11 cookies left!

    3) Synta paid 637.1062 for the watermelons? if rounded 637.11:?

    tell me which ones i got right!

    Number 2 is for people like me that lack creativity.

    Edit: As a reminder, show your work and don't stop to searching around or using online solvers. That's not really in the spirit of the thread.

    1-

    Given a triangle ABC and a point S inside. Show that, if the areas of triangles ABS, BCS, CAS are equal, then S is the centroid of ABC.

    2-

    Evaluate this purty integral.

    3-

    Suppose a mass moves smoothly enough along the x-axis. It starts at x = 0 with zero velocity and zero acceleration. At time t = 2, it reaches x = a > 0 with zero velocity and zero acceleration. Show that, at some time between 0 and 2, the rate of change of acceleration is >= 3a.

    It doesn't come easily to me at all. My degree was in music, I just really like mathematics. I've never once claimed to even be any good, and many of my old peers far surpassed me very early on. At best, I am an amateur enthusiast.

    I hope you do well in your classes, and feel free to drop in and post questions if you think anyone here can help.

    Hello, is there someone who can answer this:

    Give an example of a completely regular space X whose Stone-Cech compactification is not homeomorphic to its one-point compactification.

    I cant think of a space...

    Also:

    Prove that every locally compact, second countable Hausdorff space is metrizable.

    I can use that every regular second countable space is metrizable.

    Thank you!

    Decus, you've never told me that your degree is in music. I must admit I'm a little bit disappointed by that; If I knew earlier I'd ask you to teach me the piano, I've had that dream for quite a long time, but I think I'm a bit too old for it now ;)

    You might consider creating a thread about lessons in music b:chuckle
