It makes pdf documents manageable !! Everyone has some reason to love it! You have to need it for every day utilization to deserve to buy. You can do anything on a pdf document. Of course the basic features as to sign, insert date and page number. Highlight words, insert marks, cyrcle a word or an item.Insert an image easily. More specific features: eraser tool, text box, drop down menu (for someone to choose from) and verification of the document! All languages are supported. The cost is quite salty.. and the history version is missing. Page scroll down is a bit unconvinient that wastes me time in large 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:
