The number, 0 is nothing, so some number + 0 is that number.
Any negative number.
== The sum of any number and zero is that number.(2+0== 2) == the sum of any number and zero is that number. (2+0=2)
Zero can be expressed as the sum of any two opposite mixed number.
Yes
'a' can be any number whatsoever. The sum of +a and -a is always zero.
If you add zero to any number, the sum is the same number you started with.
If we define "opposite" as the additive inverse, the sum is zero.
7
Identity Property of Addition
Any number multiplied by zero will always give the result of zero.
I assume you mean the additive inverse. The sum of any number and its additive inverse is zero. For example, 7 + (-7) = 0.
zero and any other positive number. Any positive number and a fraction (or decimal). Any positive number and a negative number, excluding zero.
Depends what the number is. If you were multiplying and did (substitute Z with any number)0xZ,the answer would always be zero. Actually the SUM is the answer to a addition problem. So the answer would be the number in which is to 0.
Zero.
Would be that number. Example: 7+0= 7 0+7=7
The negative number.
If zero is added to a whole number the answer would be the whole number because zero is the same as nothing
