I've been traumatised for life, but I'm betting my long-lost identical twin who was raised in Germany hasn't been. For addition and subtraction are vastly easier in German than they are in English. That is, Zehneruebergang is simpler to do than regrouping, although they are basically the same thing.
You see, the "problem" with adding and subtracting two-digit numbers in English is that we process the digit in the ones position first but say the digit in the tens position first. If you had to solve the first addition card on the left, you'd add 2 to 9 to get 11, set the leftmost 1 aside on some mental side table, add the rightmost 1, 2 and 5 to get 8, pick up the leftmost 1 (if it hasn't fallen off the table in the meantime), put the 8 and the 1 together to make 81, then finally say "Eighty-one" aloud.
In German, on the other hand, the digit in the ones position is both the first to be processed and the first to be said. So you can add 2 to 9 to get 11, say the leftmost 1 aloud as "Eins," add the 1, 2 and 5 to get 8, and immediately say ". . . und Achtzig." For everyone other than savants like Bat, it can mean the difference between being on the winning team and having everyone shun you at recess. Again.
I wonder if my Maths teachers would have let me get away with saying "One and eighty."
Granted, this German advantage breaks down as soon as the numbers get a third digit. But that doesn't make it less cool.
This is a discovery I made at work, where my console always shows me two real-time numbers from the production floor: the number of people processing calls and the number of people getting some silent time. A few weeks ago, just to have something German to do, I started pretending the numbers were on flashcards and that I had to add or subtract them. And for the first time ever, maths was einfach.
If I have all that time to do maths at work, you can bet I'm not doing any writing. My job's strict limitation of employee Internet use and even stricter rule that we can't even bring pens on the production floor means that I can't draft blog posts even during slow nights. And if you do another sort of addition, you'll see that the sum of my big crafting projects plus the restrictions at work is a slower rate of blogging.
Has anything been keeping you away from your blog lately?
