```Use a CompoundExpression

Module[{a = 2},
Do[
Print[StringForm["`1` * `2` = `3`",
idx, a, idx*a]];
Print[StringForm["`1` x `2` = `3`",
idx, a, idx + a]],
{idx, 0, 3}]]

Or use a list of operations

Module[{a = 2},
Do[Print[
Column[{
StringForm["`1` * `2` = `3`",
idx, a, idx*a],
StringForm["`1` x `2` = `3`",
idx, a, idx + a]}]],
{idx, 0, 3}]]

Or use a more complex expression

Module[{a = 2},
Do[Print[
StringForm["`1` * `2` = `3`\n`1` x `2` = `3`",
idx, a, idx + a]],
{idx, 0, 3}]]
