While learning and memorizing the multiplication tables from 81 to 90 is a simple matter, it does take consistency and patience. There is no shortcut for learning times tables, you just have to keep reviewing and practicing until you have mastered each one.
For each of the times tables from 81 to 90, you can make a list of each multiple of the numbers by skip-counting, or even just writing the numbers down while using a calculator. Then, continue to review the list, and quiz yourself as often as needed until you are confident that you have it down! You can also make your own flashcards for practice if that works best for you.
