I recently read this post and the highest voted comment and it got me thinking. How does think about multiplication if it is decimals?
For example, if we have $3.9876542 \times 2.3156479$ then how would we multiply that? It doesn't make a lot of sense to add $3.9876542$, $2.3156479$ times. Then how would you think about multiplying that i.e. what's the intuition of behind that?
