What Makes Number Zero Unique?
The number Zero is very different from all other numbers; Zero
is a Whole Number but not a Natural Number.
If we say 1 Peach, we think of
. If we
say 2 Peaches, we think of
. But if
we say 0 Peaches, we picture no Peaches. So why do we have the number zero? Zero is a place holder. See examples below (hint: notice "leading zero(s)" on the left side of a number are dropped because they do
not have any meaning).
Examples Of Zero
||The value of zero is zero, so there is no change.
||There are no leading zero(s), so there is no change.
||The leading zero in this case does not mean anything.
||There are no leading zero(s) so the value does not change.
||This case looks difficult, but use the same rule. Remove the leading zeros.
There is one more very important subject about zero to talk about. No number
can not be divided by zero; this statement or rule is always true.
A important statement but why is it true? Let's answer it by example.
Assume we have ten cookies and five people at a table. We give each person an even
number of cookies; 10 cookies divided by five people means each person gets two cookies.
Perfect, everyone gets an even number of cookies.
Let's do another example. Assume we have ten cookies and one person at a table.
Again the one person at the table must get an even number of cookies; 10 cookies
divided 1 person means the one person at the table gets all ten cookies. So far
Alright, one last example. Now let's divide the ten cookies evenly among
zero people at the table. There is no way to evenly distribute 10 cookies to nobody.
In the study of math, a set of 10 cookies cannot be divided into 0 people. So 10
/ 0, at least in arithmetic, is said to be either meaningless, or undefined. Any number divided by zero is undefined!
