How
to work out magnification level
 all lenses have a number stamped on them, with an 'X'
 the 'X' stands for the magnifying power of the lens 
how much bigger it makes the object SEEM to be
 each lens magnifies the image from the previous lens...
To calculate:
Note the magnification power on the eyepiece lens
Note the magnification power on the objective lens
Multiply them together
Use Formula:
TOTAL POWER = EYEPIECE POWER x OBJECTIVE POWER
