Lets suppose we have one dimension and in this one dimension we have two points.How can we symbolize both of them or I f we want to symbolize between these numbers what should I use. Example we have 10 and 5 and I want to symbolize in this numbers and make a equation.Well it means the answer is 5 and 10 both of them.There is such a equation to make it true I thought matrix but I don't know. Simply I want to find a equation which gave me two answer or and it be a point (beacuse one dimesion) and of course this solition must be work in one dimension
