I presume you are asking what role 0 plays in that universal identity. The answer is: the additive identity. In general, the identity element in a group, ring, field etc. is the unique element (e) that does not change the value of any element (a) when you apply a binary operation to a and e. In most algebraic structures studied in elementary math, such as the field of real numbers under addition and multiplication, 1 is the multiplicative identity because a x 1 = a for all a.
yes
It Equals 2
Only 1.
Any number minus itself equals zero. Any number plus its opposite equals zero. Any number times zero equals zero.
I2 + 10 hno3 = 2 hio3 + 10 no2 + 4 h2o
negative plus positive equals to zero
2
Zero
Zero plus one equals one.
Typically, anything plus zero equals itself.
Zero is the additive identity.
The zero property because it has a zero.
