I had a problem printing a draft of a form. "Blocked plug-in". Had a chat with Paul on the site, and followed his suggestions for a fix. Then was able to print the form. I am a new user and have yet to make changes to the form and print it. Hoping for the best with that. Thanks, Verne

I have an autistic son and this PDFfiller is so amazing. There is so much paperwork between social security, IHSS, ABA therapy services, and school this gives me a few extra moments to relax

I spent approx $70 for PDF Filler, could not find a page rotate icon when I really needed it, then a screen popped up that I would have to spend $120 per year to have this additional function. I was in the midst of needing to reorient some legal documents so paid the additional money. I find this to be less than fair business practice as when I signed up there was no clear breakdown presented on the functions available for different costs.

I was in a hurry to get a commercial invoice to a broker, all went well until I tried to email the document. I'm 64 years old, so not the brightest when it comes to computer stuff, but it was really confusing at that point.

What do you like best? Easily convert PDFs to word and rotate pages withing an improperly scanned PDF What do you dislike? The text writing font options are few and when the writing box dissapears the text changes size and font that what it was displayed. Recommendations to others considering the product: More font options and ability to match font of the original document. When editing in a document your software changes the size and font of the edited text. What problems are you solving with the product? What benefits have you realized? Filling out forms and signing documents.

i=3. Ii + 1 = 34 + 45 + 56. I=1. I(i+1) = 1×2 + 2×3 + 3×4 = 20. N=1. (2n+1) = 3 + 5 + 7 + 9 = 24. And we can use other letters, here we use i and sum up i A (i+1), going from 1 to 3: n=1. N2 = 12 + 22 + 32 + 42 = 30. We can add up the first four terms in the sequence 2n+1:
Multiply the amount of numbers in the series by the sum obtained from each column addition. For example, you multiply 10, the amount of numbers from one to 10, by the average sum of 11, obtaining 110. Divide the product by two. For example divide, 110 by two.
