Is every real number a complex number?
A complex number is a number of the form a + bi, where a and b are real numbers and i is the principal square root of -1. In the special case where b=0, a+0i=a. Hence every real number is also a complex number. And in the special case where a=0, we call those numbers pure imaginary numbers. Note that 0=0+0i, therefore 0 is both a real number and a pure imaginary number. Do not confuse the complex numbers with the pure imaginary numbers. Every real number is a complex number and every pure imaginary number is a complex number also.
Are even numbers closed for addition?
Yes, the sum of any two even numbers is an even number. This means they are closed under addition. Closure Property: For every even number a, for every even number b, a + b is an even number.
What two numbers do every number greater than 1 have as factors?

Is every whole number positive?
No, a whole number can either be an even or odd number as long as it doesn't contain a fraction.Whole Numbers: 1, 2, 874687, 99, 681444NOT Whole Numbers: 1/2, 9/85, .55454---Yeah, but the question is asking if every whole number is a positive, not odd. So, yes all whole numbers are positive. If every whole number isn't positive that is saying that every whole number is an integer. Integers include positive and negative numbers and 0 on the number line. Whole numbers are 0, 1, 2, 3,... and Natural numbers are 1, 2, 3,... Integers are...-2, -1, 0, 1, 2,....

How can carbon still be considered a single element and have different mass numbers?
Every element can have different mass numbers; these reflect the number of neutrons in the atom in addition to the protons that determine which element it is.
Every integer is a complex number?
Yes. Every integer is a rational number. Every rational number is a real number. Every real number is a complex number. The complex numbers include all real numbers and all real numbers multiplied by the imaginary number i=sqrt(-1) and all the sums of these.
Is 911 the emergency number in every country?
