Interesting how different distributions are so much easier than others. Sometimes this method is dramatically better than others but it’s not so easy for me to see when. I suspect with a little more practice it should read easier and then maybe I will pick my translation faster.
Getting down to sub-second multiplication is going to take me a lot more trust in the methods and a little better selection. It’s easy when you have the answer fully memorized but when you need to read the solution from the numbers it’s tough not to start calculating rather than reading the total and that always takes a couple of seconds.
By the time I get the method sorted, I will have probably memorized much of the subset but it’s certainly an expandable idea. Once the basics are mastered, you can always mix and match with bigger sets of numbers to make things faster. There are plenty of bases you can play with as well.
Not necessarily any better than anything else but it is a nice way to play with things differently.
A fun way to play in the low double digits for a bit while I get the bugs sorted out. Brings out a nice set of subtraction problems that forces you to work the complements fast. Darn complements keep stalling my speed. Every time I hit one I find myself proving the answer by also subtracting. If I know the answer starts with 1 has 2 in the middle and ends with 3 I should be able to answer “123” without doing the addition and subtraction to get me to the same answer but I lack confidence in my methods.
Hopefully, that will sort itself out in a few weeks and I will be able to use rather than practice it in short order. I’ve also forgotten a bunch of my 2 digit squares, I can imagine them by grid location and derive them but it is incredibly handy having the facts on hand instead of noodling on them. Again they’ll be back in a few weeks but right now I feel pretty rusty.
