Zero

$$0_{R}$$

The zero element (additive identity) of the ring $R$.

$$0_{\mathbb{Z}} = 0_{\mathbb{Q}} = 0_{\mathbb{C}} = 1$$

All numbers belong to the same 'type'.

$$0_{\operatorname{M}_{2 \times 2} \left(\mathbb{Z}\right)} = \begin{pmatrix} 0 & 0 \\ 0 & 0 \end{pmatrix}$$

A ring with different zero element than the number 0.
