1-10 you memorize.
13-100 you calculate it out.
100+ you use a calculator.
11-12 is half memorized/half calculated.
I think of them as introducing you to how to calculate with larger numbers you haven't memorized.
Some of them you know - 12 * 5? 60.
But what about 12 * 7?
10 * 7 + 14. or 12 * 5 + 12 * 2.
Dealing with 11 and 12 in the times tables gives you good practice for those calculation tricks that you use for numbers greater than 12. It's not worth it to memorize an additional 44 rules but it is worth it to know how to do math.
