Place value helps simplify the multiplication of a two-digit number by a multiple of 10 by allowing you to focus on the two-digit number first and then easily add the zero(s) associated with the multiple of 10. For example, when multiplying 23 by 40, you can first calculate 23 x 4, which equals 92, and then add one zero to get 920. This approach makes calculations easier and reduces the chances of errors. Understanding place value thus streamlines the multiplication process.
