Examples of Abridged Multiplication

Arbitrary Example

Let:

\(\ds x\) \(=\) \(\ds 5.6982\)
\(\ds y\) \(=\) \(\ds 23\)

Let it be required that $z = x y$ is to be rounded to $2$ decimal places.

Then, when we calculate:

$z = 5.6982 \times 23$

we can ignore the $4$th decimal place in the partial products of $x y$.
