What is the point of imaginary numbers? Is every natural number a real number? Is 0 a positive real number? What is the meaning of imaginary numbers? Is every integer a real number? Is an imaginary number a real number? Are real numbers rational numbers?
那么a+1/a>=2倍根号（a×1/a)=2 当a=1/a，也就是a=1的时候 取等号 所以正实数和他的倒数的和的最小值是2
A real number is any positive or negative number available within the entire mathematical range of numbers. Real numbers include whole numbers, rational numbers, irrational numbers and virtually any type of number that is not an imaginary number or that can’t be computed or processed logically. ...
A real number is any positive or negative number. This includes all integers and all rational and irrational numbers. Rational numbers may be expressed as a fraction (such as 7/8) and irrational numbers may be expressed by an infinite decimal representation (3.1415926535...). Real numbers that...
