I dont understand fully what the numbers in the different type of lenses mean. For example, when it says 14-45mm (which is equivalent to 28mm - 90mm in 35mm photography)and 40-150mm (equivalent to 80-300mm in 35mm photography), what does that mean to me?

thanks in advance

These numbers refer to focal length. Smaller numbers result in a wider field of view (less zoom) and larger numbers result in a narrower field of view (more zoom, or telephoto). For regular film slr's 50mm is generally considered a "normal" view, or what the eye sees naturally. Dslr's with their crop factor due to a smaller sensor, make a 35mm closer to "normal".
