According to the IBGE Resolution 886, what should we put in the cells of a table?


a) A horizontal dash (-) when the value is zero;
b) Three dots (...) when we don't have the data;
c) Zero (0) when the value is too small to be expressed by the unit used;
d) A question mark (?) when we are unsure about the accuracy of a certain value.
