Hello. I attached a question on hydraulics that I found confusing. Mathematical back up would be appreciated! (Ignore the labels I made)

This system has got to conserve energy... which means if you have a greater force on the output cylinder than the input cylinder you've got to have a proportionately lower distance over which that force acts.
f1 s1 = f2 s2
should also be quite intuitive if you think about the hydraulic liquid - the volume of fluid leaving cylinder 1 is the same as the volume of fluid arriving at cylinder 2 - if the X sectional area of the second cylinder is greater then that volume is going to displace the second piston by less - but with greater force (because the pressure is acting on a greater area of piston)
The question is checking that you understand that you can't get more force AND more displacement at the same time for 'free' - because that would be magic.

is a topic in applied science and engineering dealing with the mechanical properties of liquids or fluids. At a very basic level, hydraulics is the liquid version of pneumatics
