Those are letters commonly used for variables. As such, they can stand for any number. A variable may refer to "any number", as in:For any number, call it "x", 2x = x + x
Or for a specific number, which has yet to be found, as in: find the value of "x", such that 2x + 1 = 7 (the solution is 3, in this example).
If you mean what is the name for what x, y, and z when used in math, then the word is variable.
X is divisible by Y if there is an integer Z such that X = Y*Z that is, Y will go into X without remainder.
A mathematical property, ~, is said to be transitive over a set S if, for any three elements, x y and z x ~ y and y ~ z implies than x ~ z. For example, "is greater than (>)" is transitive, but "is not equal to" is not.
(x - y)2 - z2 is a difference of two squares (DOTS), those of (x-y) and z. So the factorisation is [(x - y) + z]*[(x - y) - z] = (x - y + z)*(x - y - z)

If you mean what is the name for what x, y, and z when used in math, then the word is variable.
4(x)=12 2+x-y=3 x+y+z=15 4(x)-z+y=1 And in case you didn't figure it out, x is 3, y is 2 and z is 10
A binary operator, ~, defined over the elements of a set S, has the associative property if for any three elements x, y and z of S, (x ~ y) ~ z = x ~ (y ~ z) and so we can write either of them as x ~ y ~ z without ambiguity.
X is divisible by Y if there is an integer Z such that X = Y*Z that is, Y will go into X without remainder.
No. If it were, it would mean that x * (y/z) = (x*y)/(x*z) which is not true.
A mathematical property, ~, is said to be transitive over a set S if, for any three elements, x y and z x ~ y and y ~ z implies than x ~ z. For example, "is greater than (>)" is transitive, but "is not equal to" is not.
If x = y and y = z then x = z
Commutative x + y = y + x x . y = y . x Associative x+(y+z) = (x+y)+z = x+y+z x.(y.z) = (x.y).z = x.y.z Distributive x.(y+z) = x.y + x.z (w+x)(y+z) = wy + xy + wz + xz x + xy = x x + x'y = x + y where, x & y & z are inputs.
There are 8 different subsets. The null set. {x} {y} {z} {x y} {x z} {y z} {x y z}
x=abs(y+z) x=+(y+z)=y+z x=-(y+z)=-y-z
well on gamecube make a profile,exit,and on the main menu type in y,x,z,y,x,z,x,x,y,z,x,y for money or y,y,z,x,x,z,y,y,y,x,x,x for maximum reputation
The z-direction is used in upper level mathematics when the additional variable, z, is added for analysis. When this is done, equations are usually functions of x and y, with z being the dependent variable. Functions in the x-y plane are a special subset of the functions with x, y, and z, where z = 0.Algebra, Calculus and other lower math courses typically only deal with the two variables, x and y, because, as many people will attest, it is hard enough just with two variables. Therefore it is enough for all the graphs to be contained in the x-y plane and to ignore the z-direction in order for students to learn basic concepts and ideas to be used in later math courses which may add the z variable (and potentially more variables in the more abstract math courses).
