How can you use estimation to check that you have placed the decimal point correctly in your product?

An estimate will give an indication of the order of magnitude of the answer. The decimal point determines the order of magnitude and so, if the two are in agreement, then the decimal point has been placed in the right place. However, if you did your arithmetic properly then there would be no need to do the extra calculations required for an estimate.
