I thought Zero (0) is not an integer.
But I got a problem wrong in the SAT math practice, reason being ETS considers zero as an integer!

no doubt, zero is an integer. recall the defination of integers.
integers are those numbers which can be represented on number line. yep, zero is represented on number line.
thats what the reason is,!!

No difficulty Ben, let m be an integer so as that we would write x=am+b, y=cm+d and z=em+f. we will opt for to settle on m>0 and reduce than the smallest of x, y, or z so as that m> b^n +d^n-f^n which feels like a sophisticated technique so i am going to leave that to you. Now change the values into x^n+y^n=z^n, which we expect to be actual and we get (am+b)^n + (cm+d)^n = (em+f)^n and if we shrink this mod m we get, b^n +d^n = f^n mod m it truly is b^n + d^n - f^n = 0 mod m. considering the fact that m> b^n + d^n - f^n we do not have any decision yet to assign, b^n + d^n - f^n = 0 or basically b^n + d^n = f^n. Please observe that b, d, and f are smaller than x, y and z respectively, and we will stick with an similar technique back to the numbers b, d,and f to get yet another equation with smaller values say g,i,and ok so as that g^n + i^n = ok^n and we will (you are able to) attempt this continually yet we extremely can't because x,y,and z were finite integers and so we've a contradiction. note that even if if the multiple x,y,or z were unfavorable, lets rearrange them to have an equation with advantageous powers and stick with our approach. i have disregarded some information inspite of the indisputable fact that the top is basically what you required. I heard that this difficulty replaced into well known yet i do not recognize what each and every of the fuss replaced into about. humorousness all of us?

Yes, zero is an integer. It is not a natural number (1, 2, 3,...), and it is neither positive nor negative.
However, zero is still an integer (..., -3, -2, -1, 0, 1, 2, 3,...).

Yeah ZERO is definitely an integer

in computer programming 0 is definitely in the range of the integer (int) data type for a good reason. in math, it's one of the set of infinite integer numbers. integers include negative, positive, and 0
but I will tell you a secret: in computers, floating point numbers in IEEE754 format for the longest time have had a +0.0 and a -0.0 since there is a forced sign bit associated with it. This may be changing recently maybe with changes to floating point units in CPUs and in IEEE754 software FPU emulation. I think IEEE has come out with a new standard. adoption may take some time. software has traditionally attempted to take care of comparisons I think, but I don't remember for sure. sometimes comparing something with 0 doesn't work!

In math classes, zero is not considered an integer. Only positive and negative rational numbers are integers.
