Zero

Input: Zero(R)

0_{R}

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

Input: Equal(Zero(ZZ), Zero(QQ), Zero(CC), 1)

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

All numbers belong to the same 'type'.

Input: Equal(Zero(Matrices(ZZ, 2, 2)), Matrix2x2(0, 0, 0, 0))

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.
