Compute the following product mentally, using the strategy discussed in class. Show process about your thinking process, but your process should be simple enough to do it in your head without using paper and pencil $($that is what mental math is for$).$ If you take too many steps that is beyond the short term memory, your method will not be counted as a mental math strategy. You should not use any algorithm, such as partial products, standard algorithm, or the lattice method.
