Question

a 0 is equal to_______.​

Answer 1

$\large\green{\textsf{✩ Verified Answer ✓ }}$

Consider that -x + x = 0 for any x (by definition of the negative sign in front of the x).

Setting x to 0, we have -0 + 0 = 0

Because 0 is the additive identity, anything added to it is itself, which means -0 + 0 = -0

Since -0 + 0 is both 0 and -0, that means -0 = 0

a 0 is equal to 0.
