Hello stemian,
In this article i wanna share about Number 0 (Zero) ,this number is unique because so many different with other number .
Here I list about this because some people misunderstanding about zero.
- Zero is not even and not odd.
That zero is neither positive nor negative, but it's even! Easy to write. By definition, an even number is an integer that can be divided by two and the result remains unanimous. Zero is an integer and can be halved, the result is zero, and zero once again, is an integer. In addition, There is a theorem in number theory which says that the sum of two even numbers is an even number. -2 is an even number. 2 is an even number too. If summed up? The result is zero. If we assume zero is not an even number, then the theorem must be changed to: the sum of two even numbers is an even number except zero. Not effective. The math is as effective and simple as possible. Why bother?
- Zero is not a number.
If you count with fingers, it's a zero not a count. Zero is part of the counting number to indicate the quantity. When you have a box of chocolates with six bars. You can take six sticks. When your friend asks and there is no more, just say the contents of zero chocolate bar. Zero includes numbers. We are used to living in a zero-know world. But first, people do not consider zero numbers. They count from one. And before one is no number. From this assumption that zero is not a number.
- Zero is an unmarked number.
In the number system there are two signs. Positive and negative. The sign itself is not something that can be added, multiplied or got a certain operation. Positive plus positive is not there. The sign only indicates the position of the number in the number line. As a result zero it has two signs, zero positive and zero negative. But the difference with other numbers such as positive one and negative one, the sign on zero has no meaning. You know. Previously I said mathematics should be effective, so yes do not have a signature at all aja. Right. And it is. Positive zeros and zero negatives are only used in the concept of limits to describe the direction of calculation.
- Zero zero is undefined.
Some say 0 rank 0 is undefined. This is because the zero function of the ranks x and x the power of zero has a different limit value when x approaches zero. This is wrong. The X of the zero rank is 1 for all x, without exception. There is a theorem whose name is the binomial theorem. This theorem is important and should be valid for x = 0, y = 0 and or x = -y. On the contrary the zero power of the x function is not too important. Based on its importance, the zero zero is one. Instead we change the theorem right?
- Zero is tantamount to none.
The zero is there. How many x if 4 + x = 1 + 3? The answer is zero. Now how many x if 4 + x = 1 + 2? The answer is no (except negative).
Distinguish ZERO from ZERO,Many of which align them with 0 by empty Zero is there, and empty is null
Get used to spelling ZERO numbers instead of EMPTY And the application of empty words should also be taught from an early age,Such as calculus lessons emptied due to,does anyone mention the zero class? Definitely calling with an empty class,if I am a math teacher, someone who say empty yes I empty the value too
