PDFfiller saved me significantly more than the cost of a subscription
I found PDFfiller when searching for a (lease) document I needed to complete for a potential tenant. I signed up for the trial, and I will let it continue to a paid subscription. PDFfiller saved me significantly more than the cost of a one-year subscription. I'm really happy with the program, which allowed me to customize the document, and easily fill out the form.

The products are awesome and have been essential to the success of my business!
The forms are very easy to access and to use. The ability to have access to such a variety of forms especially IRS forms. The freedom of use to so many forms and the ability to upload your own created forms far exceeds so many other products that have so many limitations on the use of their products.
My only complaint is that sometimes it is a little difficult to find certain forms that you are looking for but it is usually remedied rather quickly.

Perfect for merging multiple JPG images into a compact PDF
This app / web page allowed me to easily merge six JPG image files (each 2550x3300 pixels, some included photos) into a single compressed PDF document that was small enough (7MB) to be easily shared as an email attachment. Did exactly the job I wanted it to!

What happens when you add two logs?
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. The same base, in this case e, is used throughout the calculation.
How do you add two logs?
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 two logs are multiplied?
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.
