In computational complexity, the logarithmic time hierarchy (LH) is the complexity class of all computational problems solvable in a logarithmic amount of computation time on an alternating Turing machine with a bounded number of alternations. It is a particular case of a bounded alternating Turing machine hierarchy. It is equal to FO and to FO-uniform AC0. The th level of the logarithmic time hierarchy is the set of languages recognised by alternating Turing machines in logarithmic time with random access and alternations, beginning with an existential state. LH is the union of all levels. (Wikipedia).

The chaotic complexity of natural numbers | Data structures in Mathematics Math Foundations 175
This is a sobering and perhaps disorienting introduction to the fact that arithmetic with bigger numbers starts to look quite different from the familiar arithmetic that we do with the small numbers we are used to. The notion of complexity is key in our treatment of this. We talk about bot

Divisibility, Prime Numbers, and Prime Factorization
Now that we understand division, we can talk about divisibility. A number is divisible by another if their quotient is a whole number. The smaller number is a factor of the larger one, but are there numbers with no factors at all? There's some pretty surprising stuff in this one! Watch th

Understanding Limits and L'Hospital's Rule
We learned about limits earlier in this series. We know what they represent, and we know how to evaluate them. Then we found that we don't need them that much, because we have better methods for differentiating functions than all that business with tangent lines and limits. But limits stil

Analyzing Sets of Data: Range, Mean, Median, and Mode
What does the word "average" mean to you? There are a lot ways we use that word, and even in math, it can imply a few different things. If we want to summarize a set of data in a meaningful way, we can talk about the mean, the median, or the mode, and one might be more useful than another
