Most advanced photographers are quite a bit older than you. They learned photography using a 35mm film camera. Now the 35mm film camera has be around for nearly 100 years, so these serious photographers are also highly familiar with lenses they used with this camera.
Time marches on and the majority of digital cameras are smaller than the venerable 35mm film camera. So when they purchase a compact digital, they like to compare its shorter lenses to the longer lens associated with the bigger camera of their youth. Thus the equivalency was born. Your camera is about 4 ½ times smaller than the old 35mm film camera. This is called a magnification or crop factor. Multiply your camera’s lenses by about 4.5 and that what focal length would do about the same job on a 35mm film camera. My advice is to ignore this data for now.
