My 2 year old son loves numbers. He can count by himself well into the 50s and can tell you what number he's looking at to at least as high as 110. As for me, well, numbers and I have never been the best of friends. How can I, a numbers-adverse dad, encourage and nurture his talent? [more inside]
What is the slowest-growing non-repeating, non-trivial* whole number sequence? [more inside]
My math knowledge ends just past Newton. What books provide a good, relatively general-audience introduction to the past 150-250 years of problems and developments in mathematics? [more inside]
Can a transcendental number such as pi, be raised to an irrational, but algebraic power resulting in an algebraic solution? Complex solutions would be acceptable. There might be a quick proof here, or there might not be. - Thanks for any help you can offer answering this! (And I promise that this isn't for a class or anything like that!)
I'm a 21 year old college senior liberal arts major who has managed to slide by in school (and life) without ever really learning math beyond a middle school/very early high school level. For no reason in particular, I've decided that I want to get serious about bettering myself in the math department. How can I teach myself the academic math skills I missed out on? [more inside]
What is the difference between floating point accuracy and precision?
My favorite number is 0. I have many reasons for this, but I want more. [more inside]
What are some cool math and number facts that would blow the mind of a seven year old? [more inside]
In a talk (at TED) by Brian Greene on string theory he says that there are "there appear to be about 20 numbers that really describe our universe..." He lists a few in his talk, but what are the rest of of those numbers? [more inside]
Does anyone have experience with self-treatment as an adult with dyscalculia? I think I may have it, and that I've had it all my life. Whether or not that's so, are there any tricks to "rewiring" yourself? [more inside]
My son asked me how many trees there are in the world. I know there are a finite number, yet I also know that it is not practical to count them. Same with grains of sand. When the set cannot be measured because it goes on forever we say the set is infinite. Is there a single word to express the concept of a countable, finite number too large to actually count?

Why is it hard for me to perform simple mental calculations with certain numbers? [more inside]
Can you help me with my innumeracy? [more inside]
This page mentions, among other things, that "100 is the smallest square which is also the sum of 4 consecutive cubes." Obviously, this refers to the sum of 1^3 (1), 2^3 (8), 3^3 (27) and 4^3 (64). But it seems to me that the sequence can be pushed back to start with 0^3 (0), in which case you can get four consecutive cubes adding up to 36, which is a square. Is zero then not considered a cube?

I read The Curious Incident of the Bear in the Night-Time and one of the bits of cleverness is using primes to number the chapters. This got me thinking, is it possible to have a base prime number system? [math inside] [more inside]
The Number Zero: odd, even, or neither?
