what are two numbers that are equal to each other?

Question

Two numbers that are equal to each other? i have been recently been asked this question and the person who asked me wouldn't say if it is a trick question :( i have no idea please help!

Answer 1

There aren't any two *distinct* numbers that are equal to each other. The definition of equality necessarily says that if x = y, they are the same number. So, I suspect this may be a trick question.

(Oh, and to the respondents above me: there is such a thing as - 0; it happens to be equal to 0. The negative of a given number x is its additive inverse, ie. the unique number -x, which, when added to x, yields zero. And as 0 + 0 = 0, -0 = 0.)

Answer 2

What kind of question is that? You might as well ask how much does something have to weight to weigh 2 ounces? And there is NO SUCH THING AS -0! lol help yourself to a math book dude

Answer 3

it is a tricky question indeed, but try this:

if 1! = 1, and 0! = 1, then 1 = 0

Answer 4

1=1, 2=2,3=3, 4=4, 5=5, 6=6, 7=7, 8=8, 9=9, 10=10, 11=11, 12=12, 13=13, 14=14, 15=15..................................................

Answer 5

know wat ???
1=2 !!!

want the proof ?? look into this...

Consider that a=b,

multiply by 'a' on both sides,
-> a^2=ab

subtract b^2 on both sides,
-> a^2-b^2=ab-b^2

we know by identity that a^2-b^2=(a+b)(a-b),
->(a+b)(a-)=ab-b^2

taking 'b' as common out from the RHS,
-> (a+b)(a-b)=b(a-b)

cancelling (a-b) from both sides,
-> (a+b)=b

but since a=b as per our assumption,
-> b+b=b

that becomes,
-> 2b=b

cancelling 'b' on both sides,
-> 2=1 !!!

got the proof ?!?!?

now if u r clever enuf, find out the flaw in the above solution !!!

Answer 6

Minus zero and zero

Answer 7

yeh it is a trick question

minus zero lol where do u do ur maths? lol
