What are good online calculations?
"First of all, that do not have long to find the network needed programs, swing them, with terrible cursing, with all sorts of sharing services, puts up with them free of charge and, accordingly, the polyfunctional versions bother installing any software on the system, do not deal with them often very confusing interface.
For all online payments are always much easier and more comfortable - there are mandatory forms, fill them, click "calculate" or something performs the function of running a script, and everything - the result is ready! "(Source: https://povny.blogspot.com )
Why register?
Unregistered users can not use all the features of the calculations "Online Electric. For such users - guests, is available only introductory version of the system, limited input of initial data for calculations, reports, etc.
Users can then simply register and use the payment system online. Scripts allow you to perform an unlimited number of calculations and generate reports in Word.
