because no number is exactly like it... Like a person. They can have a lot in common but there is one thing the other doesn't have that is unique :)
1/0
$0 as of 2012.
Digits or decimal digits more specifically. The decimal system has 10 unique digits 0-9.
The additive identity for a set S is a unique element, 0, in the set such that 0 + x = x = x + 0 for all elements x in the set.
No, for any base, there is no digit that represents the base, you go to the next higher place. For example, in base-10, there are ten unique digits (0-9) Base 2, there are 2 unique digits: (0-1) So for base five there would be 5 unique digits (0 through 4). To represent a five, in base five would be 105
Addition is: Commutative ie a + b = b + a Associative ie (a + b) + c = a + (b + c) so that they can both be written as a + b + c Existence of Identity: There is a unique number, 0, such that a + 0 = 0 + a = a for all numbers a Existence of Inverse: For any number a, there is a unique number b such that a + b = b + a = 0. This b is written as -a.
They all are one digit number
An animal in the tundra that is unique is the polar bear. The fact that it just has to eat to keep itself warm is amazing. It can also swim in 0 degrees water.
Answer: 2The values are 0 or 1.
There are 45 combinations.
That is not necessarily true. A zero at 0 produces a unique answer as often as it does elsewhere, and a multiple multiple answer as often as it does elsewhere.
Initial Value Problem. A differential equation, coupled with enough initial conditions for there to be a unique solution. Example: y'' - 6y = exp(x) ; y'(0) = y(0) = 0
