Get the Logarithm mug.MATHEMATICS: The exponent, or power, to which 10 has to be raised to express any positive real number.
Logarithm is derived from Greek logos "reckoning, ratio," and arithmos "number."

Since I can't make a nice table, let's use the following format: Base, Exponent, Expression, Result such that in line 1, Base = 10, Exponent = -3, Expression = 10^-3, Result = 0.001. We obtain,
10, -3,10^-3, 0.001 (or 1/1000) (line 1)
10, -2, 10^-2, 0.01 (or 1/100)
10, -1, 10^-1, 0.1 (or 1/10)
10, 0, 10^0, 1
10, 1, 10^1, 10
10, 2, 10^2, 100 (10 squared)
10, 3, 10^3, 1,000 (10 cubed)
And so forth.
Any positive real number can be expressed as the product of 10 raised to any real number; for example 100,000 can be written as 100 x 1000 = 10^2 x 10^3 = 10^5. Notice that the exponents are additive. It is easy to show that for division the exponents subtract.
Before the advent of hand-held electronic calculators, logarithms and the use of log tables reduced calculating time by converting long-hand multiplication into an addition process and long-hand division into a subtraction process where the result was accurate to three significant figures. One would just look up the logarithms of two or more numbers that were being multiplied, sum the logarithms, and then look up the corresponding number.
Another benefit of using logarithms is that curvilinear data points can be converted into linear data points, and the latter is easier to model with a first-order equation derived using either graph paper or linear regression analysis.

Get the Logarithm mug.epic, lavish, busy.. we really don't know the true meaning. It is something Chris said one day (see example below).
- those were a good couple of nights
- indeed they were, that was a pretty lagarous week then seeing as we had beach party right before travelling

Get the logarithic mug.Di aria of the mouth; can't control the words coming out of the mouth; one has no idea what they are saying in a sober state of reality. This is not to be confused with tweeker talk, this is a real disease.
The loss of meaning of words.

Get the Logaria mug.The most crappy (C-RRRR-AAAA-P-EEEE) subject in the world. Logarithms tell how many times a number x must be divided by the base b to get 1, and hence can be considered an inverse of exponentiation. Yeah, whatever!
Me: I have been trying to understand this logarithm crap with its shitty tables for the past seven weeks.
He: Yuck!
