So what's log?

# Math on Paper Compared to iPad (Addition, subtraction, algebra, etc.)

log is just logarithm like

log_{3}9 is 2

It basically asks 3 (tiny number) to what power is 9 (the the bigger number)

ln is the same, but log_{e}the number for all

~~log by itself is usually log~~ no, i'm wrong it's what buildy said below here_{10}

Log_{b} x is asking b to what power equals x

So Log_{2}(64)=6 because 2^{6}=64

Log by itself with no base is ln, the natural log (log base e).

**BuildASnowman**#1423

It actually depends - in most programming languages and in mathematics itself, log(x) is the natural log. But, in engineering it is usually log10(x). Which is weird.

oh, that makes sense then. :)

I randomly found this lol http://www.mclph.umn.edu/mathrefresh/logs.html

Nope E is euler's number, probably one of the most important mathematical constants ever. Objectively better than pi. But pi is better.

@BuildASnowman, since you're good at math, isn't DAS bad? Can you get her to log on so we can see?

I can think of one thing. I hate math on paper and on iPad. But the iPad is more accurate. Because it calculates it. Wait, no, the human brain I guess actually is more accurate. Because it can not break or anything. I dunno. What do you guys think?

**BuildASnowman**#1435

The human brain is faster than an ipad or computer by a long measure, and also way better at math. Computers can do brute force calculations fast, but anything past 5th grade math is usually past the limits of an ipad.
