What do you like best?
Easy to use but comprehensive options for editing. Quick and efficient which is important with time sensitive docs and a busy life. Some recent new features tells me the company is progressive. I was having technical difficulties one day and support was responsive. I've tried numerous PDF/Editing programs. and this is by far my favorite. It's web based not some ap that you have to download that later crashes your computer. Can access it from any PC so that helps too.
What do you dislike?
The price is substantially more that I'd like to see. Takes a bit to save file to PC once done editing. can be a little slow at times but still a reliable tool I use at least weekly if not daily. Something in the $50 range would be delightful and it's well above that currently. Maybe efax for this price I have not used the esign feature yet so maybe will try that given our member benefit program is lapsing.
What problems are you solving with the product? What benefits have you realized?
Quick way to edit and correct documents. Easy to save and access later. Lots of options for composing sending and revising. I only use basic functions but there are several ways to use this valuable tool beyond the features I use that exceed other competitors.

Intro to Adding and Subtracting Logs (Same Base) Logs of the same base can be added together by multiplying their arguments: log(XY) = log(x) + log(y). They can be subtracted by dividing the arguments: log(x/y) = log(x) — log(y).
Intro to Adding and Subtracting Logs (Same Base) Logs of the same base can be added together by multiplying their arguments: log(XY) = log(x) + log(y). They can be subtracted by dividing the arguments: log(x/y) = log(x) — log(y).
With exponents, to multiply two numbers with the same base, you add the exponents. With logarithms, the logarithm of a product is the sum of the logarithms. Use the product property to write as a sum. Simplify each addend, if possible.

What is the rule when you multiply two values with the same base together (x2 * x3)? The rule is that you keep the base and add the exponents. Well, remember that logarithms are exponents, and when you multiply, you're going to add the logarithms. The log of a product is the sum of the logs.

When they tell you to “simplify” a log expression, this usually means they will have given you lots of log terms, each containing a simple argument, and they want you to combine everything into one log with a complicated argument. “Simplifying” in this context usually means the opposite of “expanding”.
A logarithm is the power to which a number must be raised in order to get some other number (see Section 3 of this Math Review for more about exponents). For example, the base ten logarithms of 100 is 2, because ten raised to the power of two is 100: log 100 = 2.
remove parentheses by multiplying factors. Use exponent rules to remove parentheses in terms with exponents. Combine like terms by adding coefficients. Combine the constants.
