Hi guys how are you i have a question why does people delete questions and answer from and where is the delete option?

Just fine. No idea I was also trying to find about that

I've also seen in my notifications that some user has deleted your answer to question

professionals can use many types of technology that can them. some examples are, computers (they research and can use for programs for data, they are also used for job applications, school work, and even to make new ideas), speedometers (can get data for unknown data), sometimes something as small as a pen (used for rough drafts, to insert data, and again job applications).
