What is zero plus zero?

Actually you are right.\n\n2 times y, limit y->0  = 2.y\n\nSo it is twice of the original.\n\nBut the "value" of 2.y is still 0. \n\nActually let me explain the significance of this, (which is the basis of calculus). Suppose somebody asks you what is 0/0, then you cannot answer, because there is no answer. \n\nBut if the same person asks what is y/y, where y is close to 0. (This is denoted by y->0) , you will obviously say the answer is 1.\nThat is why, this kind of analysis is important.

means zero or nothing.  40-love = 40 - zero

Neither of them are real in the normal sense of the word.\nThey are both abstract ideas for concepts we innately understand. One is the concept we understand to represent the cardinality of a lone object. Zero is the concept of the cardinality of the empty set.\n\nThere are symbols for 0 and 1 that we can use in arithmetic manipulations, but 0 and 1 are not real objects.\n\nKind of similar to "red" you can have a red car, a red barn, a red light, but you can't have a red, it doesn't exist except as a description of something else.\n\nMathematically, both are real since the real numbers are and extension of the rationals which are an extension of the integers and zero and one are both integers.

you just add the inputs, and the result (the least significant digit) is the answer you need:\n\n0+0+0=0\n0+1+0=1+0+0=0+0+1=1\n1+1+0=0+1+1=1+0+1=10 ->0\n1+1+1=11 ->1\n\nIf you like to solve it by boolean 1+digit adding, then,\nlet you entries be a,b,c\nr1=a.not(b)+b.not(a)\nr=r1.not(c)+c.not(r1)\nwhere . means and

"Division by Zero in mathematics is undefined because no definite meaning can be attached to this operation. To understand this, notice that a/0=b must (if it means anything) mean the same as a=0•b.\nHowever, if a≠0 then a=0•b is not true for any b; and if a=0 then a=0 is true for every b. This tells us that a/0 cannot be assigned a definite value- and therefore has no meaning."    --George Simmons

Infinity\n\nAddendum:\n\nI was astonished to see that the majority of answers are not converging on infinity, as I had learned in school. So I did a little more research. \n\nIt definitely remains as the mathematical definition that Z/0 = infinity for any non zero value of Z. However, as computers cannot process infinity, calculators etc., all show error or undefined. Modern applied mathematics are now teaching contexts where the result is defined and contexts where it should be considered undefined.\n\nAlthough its clear infinity is still the text book answer, it is also clear than in a practical sense infinity has no value and you still need to code around the case in your calculation software.\n\nLook below for many of the sites that discuss this.

0 is the cardinal of the empty set. Thats the mathematic rigurous definition. Before that, zero was defined conceptualy, as "no object", "nothing", "none", in order to define the quantity/measure of "nothing".

bcoz 0 is the additive identity and any number multipled by 0 gives 0.So operations using 0 are simpler and life becomes much more easier.

This can't be answered either "true" or "false". Integers comprise the set of whole numbers (1,2,3,...) A positive integer and a negative integer will have a sum of zero if their absolute values are identical.(Absolute value is defined as the difference between a quantity and zero.So+1 and-1 have identical absolute values and their sum is zero, but +1 and -2 do not have identical absolute values, so their sum is not zero{it is, in fact,-1}).

VERY GOOD Question!!!\nI don't know, but i never thought abou it either.\n\nwell if you only need to write 0 i guess you don't write anything. and for like 10 you just write an x so i guess there is not a zero because you don't really need it.\n\ni hope i was help!

another zero would be the conjugate of the one you know,\nthen try the rational zeros test, or even syn div

anything to the power of zero is one. so 1+1=2. Y=2. 2X2=4.

The additive inverse is what you add to anything to get zero.  That means it's the negative!  Of course, the additive inverse of a negative (negative of negative) is positive.\n\ne.g. -4 + 4 = 0 and so each of 4 and -4 is the additive inverse of the other.

Your statement translates to the following algebraic equation.\na+b=a-b=a*b\nSolving a+b=a-b, we get b = 0; \nSubstituting b=0 and solving a+b=a*b, we get a = 0;\nSo the two numbers are zeroes.
