Mnemonic

Tartaglia's poem is a mnemonic for the solution of the cubic equation:

When the cube and its things near
Add to a new number, discrete
Determine two new numbers different
By that one; this feat
Will be kept as a rule
Their product always equal, the same
To the cube of a third
Of the number of things named.
Then, generally speaking
The remaining amount
Of the cube roots subtracted
Will be our desired count.
