Well I paid for the year then could not access a file I did the same day. Then I sent my accountant a file via attachment since he says "not technical" & could not open it in pdfiller file, so I sent as attachment so he could complete but he could not so he wrote it in now I have to complete it & paying him the same.

Sometimes the system will not allow me to download the forms I've edited. Sometimes there are glitches in the system that prevent us from logging in and saving documents. Sometimes system can be a bit slow, I notice it more in the afternoon where people may use the system more.

I liked the flexibility to edit and make changes in my document.
Its rare to get something like this, especially for a pdf format. for me it made things easier as I was working on a pdf document and I wanted to make a few changes on it without converting to a word document.

Quick download, easy fillable PDF forms online
very practical online fillable forms but using the snail mail from the IRS, i was able to obtain the same forms via mail a week later. I like its free trial but only needed the 2022 W2 form and not the entire services

What do you like best?
This platform is so easy to use. I usually get very annoyed with pdf files as most of the other websites I have tried have been a complete pain to make the adjustments I need. PDF filler allowed me to easily add the information, download, and save with my personal E-signature with my toddler on my lap ! I am very happy that I found them and will continue to use them for all my conversion needs.
What do you dislike?
I haven't really found anything that I dislike just yet. The monthly subscription is a bit pricy if you won't be using it often enough so maybe they could have pricing for example 4 downloads monthly etc.
Recommendations to others considering the product:
I would recommend
What problems are you solving with the product? What benefits have you realized?
I have been able to fill out pdf forms to submit documents online. It saves the time of printing the pdf, filling it out and then scanning.

How do you calculate logarithms?
Logarithm, the exponent or power to which a base must be raised to yield a given number. Expressed mathematically, x is the logarithm of n to the base b if bx = n, in which case one writes x = logo n. For example, 23 = 8. Therefore, 3 is the logarithm of 8 to base 2, or 3 = log2 8.

How do you find the negative log?
In particular, the logarithm of a negative real number x can then be calculated as log(x)=log(|x|a)=log(|x|)+log(a)=log(|x|)+i. For all KZ. Therefore, the complex logarithm is only defined up to multiples of 2i ! Or maybe log(x)=log(|x|ei1772)=log(|x|)+log(ei1772)=log(|x|)i1772.

How do you add a negative log?
A common technique for handling negative values is to add a constant value to the data prior to applying the log transform. The transformation is therefore log(Y+a) where an is the constant. Some people like to choose a so that min(Y+a) is a very small positive number (like 0.001). Others choose a so that min(Y+a) = 1.
