Google search is very common thing to our daily life. Whatever thing that we do not know, we google-ing. Solutions from the form of texts to images to websites to whatever lalalal thing you can imagine, you are able to find it by doing Google search.
For me, after almost 28 years I live in this simple yet complicated world, I only know that we can do mathematic calculation using Google search also.
As simple as 1+3
Or a little bit complicated one
Even used as currency converter
Not sure what else it can do beside normal search purpose, so you can explore it yourself :)
