addition and subraction of vectors and uses of vectors in our daily life

“Daily life” is different for different people. For me as a teacher uses it in my daily life for teaching students. Students use it for learning. Pilots use it for takeoff and landing of planes. Scientists and Physicists ofcourse use it in their daily life. Engineers use it. Computer programmers use it. But probably shopkeeper, fashion designer, Chartered Accountant, Lawyer etc dont use it in their daily life.
