Are real numbers closed under subtraction?
Yes, real numbers are closed under subtraction. This means that when you subtract any two real numbers, the result is always another real number. For example, if you take two real numbers, such as 5 and 3, their difference (5 - 3) is 2, which is also a real number. Therefore, the set of real numbers remains intact under the operation of subtraction.
What operation gives you the sum of 2 numbers?
The operation is called addition.
Are 1 and 2 real numbers?
Yes they are real numbers
What is the range of fx equals 2-3x?
The range is the all the possible y-values for the function. f(x)=2-3x does not have any points where it is undefined because it is a linear function ( a line). The answer is all real numbers or (-infinity,infinity)
The meaning of range in algebra term?
Given a function f(x), the domain is all of the numbers you are allowed to put in it (in other words x), and the range is all of the numbers you can get from it (in other words f(x)).Here are a few examples:f(x) = 3x+2D: All real numbers (-inf,inf)R: All real numbers (-inf,inf)f(x) = |x| + 2 (where |x| is the absolute value of x)D: All real numbers (-inf,inf)R: All real numbers greater than or equal to 2 [2,inf)f(x) = 1/(4x^2-1)D: All real numbers except 1/2 and -1/2 (because if you plug in either of those you get 1/0 which is undefined) (-inf,-1/2) u (-1/2,1/2) u (1/2,inf)R: All real numbers greater than or equal to -1 except 0. [-1,0) u (0,inf)
What are the rules governing in operation of whole numbers?
Whole numbers are governed by several basic arithmetic rules: they can be added, subtracted, multiplied, or divided (except by zero). The commutative property applies to addition and multiplication, meaning the order of the numbers does not affect the result. The associative property also applies, allowing for grouping of numbers without changing the outcome. Finally, division by zero is undefined, and any operation must maintain the integrity of whole numbers, which are non-negative integers (0, 1, 2, 3, etc.).
Do 0 and 3 have closure for addition?
A set of numbers is considered to be closed if and only if you take any 2 numbers and perform an operation on them, the answer will belong to the same set as the original numbers, than the set is closed under that operation. If you add any 2 real numbers, your answer will be a real number, so the real number set is closed under addition. If you divide any 2 whole numbers, your answer could be a repeating decimal, which is not a whole number, and is therefore not closed. As for 0 and 3, the most specific set they belong to is the whole numbers (0, 1, 2, 3...) If you add 0 and 3, your answer is 3, which is also a whole number. Therefore, yes 0 and 3 are closed under addition
Is a real number a whole number?
No, not all. All numbers are Real Numbers. * * * * * All numbers are not real numbers: there are complex numbers and others. Also, all real number are not whole numbers. sqrt(2) or pi, for example are real numbers but not whole numbers.
Are real numbers real?
Yes. :S real numbers are real numbers. 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
Find the domain and range fx3x-2?
the domain is all real numbers and the range is all real numbers the domain is all real numbers and the range is all real numbers
What was operation aurora world war 2?
It was fake it isn't real
What arithmetic operation can be preformed on the numbers from this sequence -3-2-10123?
Any arithmetic operation, other than division by zero, can be performed on any set of numbers in a sequence.
