Given two numbers, x and y their difference is |x - y|. |x - y| = x - y if X ≥ y and |x - y| = y - x if x < y
The properties for real numbers are as follows:closure: for any numbers x and y, x + y is a real number.associativity: for any numbers x, y and z, x + (y + z) = (x + y) + z = x + y + zidentity: for any number x, there is a number, denoted by 0, such that x + 0 = x = 0 + xInvertibility: for any number x, there is a number denoted by -x such that x + (-x) = (-x) + x = 0Commutativity: for any numbers x and y, x + y = y + x.
If the two numbers are X and Y, it is |X - Y| + 4 or abs(X - Y) + 4
Try system.X + Y = 62X - Y = 36X + Y = 62- (X - Y = 36)X + Y = 62- X + Y = - 36------------------------------add2Y = 26Y = 13==============The numbers.
There are two simple strategies to compare two numbers, X and Y: you can calculate X - Y. If X - Y > 0 then X > Y, if X - Y = 0 then X = Y and if X - Y <0 then X < Y. Or you can calculate X/Y. Provided both are greater than 0, if X/Y > 0 then X > Y if X/Y = 1 then X = Y if X/Y <1 then X < Y
Given two numbers, x and y their difference is |x - y|. |x - y| = x - y if X ≥ y and |x - y| = y - x if x < y
Let x and y be two positive numbers. The cases are: x > y, then x - y > 0 x = y, then x - y = 0 x < y, then x - y < 0
If you have two numbers, X and Y and you want X as a percentage of Y then the answer is: 100*X/Y

The difference (x-y) between two whole numbers, x and y, is whole and is positive, if x > y; zero, if x = y; and negative, if x < y.
If the two numbers are X and Y, it is |X - Y| + 4 or abs(X - Y) + 4
When X and Y are prime numbers X + Y is even unless either X or Y = 2. (As 2 is the only even prime number)
Try system.X + Y = 62X - Y = 36X + Y = 62- (X - Y = 36)X + Y = 62- X + Y = - 36------------------------------add2Y = 26Y = 13==============The numbers.
{x+y=51, x-y=26} x=38.5 y=12.5

We have the numbers x and y. x+y=120 x-y=50 2x=170 x=85 y=35
The two numbers are 18 and 36. Let the two numbers be x and y, then: x ÷ y = 2 ⇒ x = 2y x + y = 54 ⇒ 2y + y = 54 ⇒ 3y = 54 ⇒ y = 18 ⇒ x = 2y = 2 x 18 = 36
