Answer:
Explanation:
It is generally not possible to multiply two very large numbers using just your head without any tools or aids. Multiplying large numbers requires a significant amount of mental effort and can be prone to errors, even for people who are skilled at mental math. In order to perform the multiplication accurately, it is typically necessary to use some form of written or visual aid, such as pencil and paper or a calculator.
There are a few mental math techniques that can be used to simplify the process of multiplying large numbers, such as using the distributive property or applying the associative property of multiplication. However, these techniques are usually only effective for smaller numbers and become less practical as the numbers get larger.
In general, it is more efficient and accurate to use a calculator or a computer to multiply large numbers, rather than trying to do it mentally. These tools are designed to handle large calculations quickly and accurately, and can save a significant amount of time and effort.
