why? for example, I want to connect one computer and get the maximum download speed from 3 WANs at once, is this possible? Or is it not possible?

Its only possible to fully aggregate the speed if the application using the bandwidth is both multi-connection aware and capable, most "usual" software isnt really, and multi connection has to be supported both ends, including whatever ultimately recieves the traffic at the other end on the internet

 

Okay, got it that it is impossible to get the TOTAL speed, but only divided.
