difference

Sir,

 

The difference of two number is always

 

1.equal to one number or less than both the number.

 

IS (1) correct? Could you please explain it to me?

 

Thanks.

if x is the first number and y is the second number, then the difference between them is equal to x-y. More simply, the difference is the answer to a subtraction problem.

Hello!

 

No,MY question is some what diffrent.

 

I want to that difference of X-y is always

 

equal to Y or less than X,Y.

 

Thanks.

Ummm, are we assuming only positive integers? because if we're not then I believe the problem is impossible.

 

If positive non-zero numbers are assumed then x-y<x. That seems bloody obvious but it seems to be what your asking.

Teachers!

 

Sorry!I could not mention that I am talking about only positive integer.

 

SO, x-y <x or x-y =y.

 

 

Thanks.

Say X = 5 and Y = 2 then X - Y = 5 - 2 = 3

So the difference = 3 and X > 3 and Y < 3

So in this case the difference is not less than both numbers.

 

Are there any numbers where the difference is less than both numbers?

 

Say X = 5 and Y = 7 then X - Y = 5 - 7 = -2

-2 is said to be less than 5 and 7 because -2 is to the left of zero on a number line.

So the difference between two positive numbers is sometimes less than both numbers and sometimes more than both numbers

 

Can X - Y = X ?

If X = 2 and Y = 0 then 2 - 0 = 2

So the answer is yes.

 

Can X - Y = Y ?

If X = 2 and Y = 1 then X - Y = 2 - 1 = 1

So the answer is yes.

 

Can X - Y = X or can X - Y = Y for every pair of numbers.

 

Try it for yourself

"Say X = 5 and Y = 2 then X - Y = 5 - 2 = 3

So the difference = 3 and X > 3 and Y < 3"

True, but the question said just two numbers, so the example doesn't fit the question.

"True, but the question said just two numbers, so the example doesn't fit the question." Never mind, I wasn't looking at it right
