Multiply the objective lens (the one facing your specimen) with the ocular lens (the one through which you look). Most ocular lenses are 10x. So, a 10x ocular multiplied with a 40x objective lens would be 400x.

Remember: magnification of a microscope is directly proportional to the resolution of the microscope and inversely proportional to the wave length of light used.
