It has its limits Just like finding out the answer to any number multiplied by nine between one and nine. Where you take the number before the number you're trying to multiply with nine then find out what number added to it will equal nine then put the two numbers together and that is your answer. An example is 9 * 7 = 63 The 6 from 63 comes before the 7 from 9 * 7 and 3 added to the 6 will equal 9.
