-23 + 23 = 0
112-89 = 23
234 = 23 x 23 x 23 x 23 = 279841 235 = 23 x 23 x 23 x 23 x 23 = 6436343
-23 - 23 = -46
A hydraulic system multiplies force by transmitting pressure to another part of a confined fluid. This is achieved by using a hydraulic pump to create pressure in the fluid, which is then transmitted through a connected system of valves and cylinders to perform work, such as lifting heavy loads.
23 + (-23) = 23 - 23 = 0 so yes.
