Great online pdf editor. Should have more features in personal level, a bit annoying to not be able to perform basic functions such as erasing sections of a document or deleting pages in a commercial, paid product. That is my only complaint though. Great software otherwise.

PDFfiller lets me print out a nice looking form for school physical exam. It is harder to use than manually writing on a school physical form. However, there are fewer mistakes on a printed version from a computer than sometimes I found when I had to manually fill out a previous version of a school physical form. Thank you.

Very easy to use. Have saved me so much time.
Saves time by not having to re-type documents and I can just add in names on pre-typed forms. It has been instrumental for changing contracts and names on documents
I think, if it isn't in place, a way to be able to use it on your mobile device. Most often, I'm on the go and things have to be changed or modified. This could be huge for a busy person like me.

If you want a great PDF software with support you cant go wrong with PDFfiller
Yesterday, I needed assistance with a PDF, which, when it was submitted to PDFFiller, would change the computer bar and make it into numbers. Since I needed this document in its original form, I contacted their customer service, and Kara helped me. Kara went out of her way to make sure my problem was resolved. It was really nice to talk to a real human instead of a bot, and that human being was so kind and able. My problem is not completely resolved, but she taught me how to be able to fill the PDF without losing the bar and eventually make a template, which is what I need to do. Awesome team-mate, you got there, PDF Filler!

How do you sum a log?
A useful property of logarithms states that the logarithm of a product of two quantities is the sum of the logarithms of the two factors. In symbols, logo(XY)=logo(x)+logo(y). (x y) = log b (x) + log b
How do you find the sum of a log?
A useful property of logarithms states that the logarithm of a product of two quantities is the sum of the logarithms of the two factors. In symbols, logo(XY)=logo(x)+logo(y). (x y) = log b (x) + log b
What is the formula for log a log B?
The identities of logarithms can be used to approximate large numbers. Note that logo(a) + logo(c) = logo(ac), where a, b, and c are arbitrary constants.
How do you add logs together?
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).
What happens when you add logarithms?
The laws apply to logarithms of any base, but the same base must be used throughout a calculation. This law tells us how to add two logarithms together. Adding log A and log B results in the logarithm of the product of A and B, that is log AB. The same base, in this case 10, is used throughout the calculation.
What is the addition rule for logarithms?
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.
