The story of the past 3 years ...

I like skiff but I feel they take some privacy shortcuts compared to say tutanota, which is very good but clunky.

Trachtenberg starts from the right like regular multiplication, but doubles and halves instead of memorising the times tables. Carried numbers are maximum 2 so there is very little room for simple errors.

The rule for 12 is "double each number in turn then add its neighbour". The neighbour is the number to the right.

So 12 x 123456 would be:

Double 6 plus 0 = 12. Keep the 2 and take the 1 to the next number.

Double 5 plus 6, plus the 1 from 12 = 17. Keep the 7 and carry the 1.

Double 4 plus 5, plus carried 1 = 14. Keep 4, carry 1.

Double 3 plus 4, plus the carried 1 = 11. Again carry 1.

Double 2 plus 3, plus the carried 1 = 8.

Double 1 plus 2 = 4.

Finally there's always an invisible "0" at the start of each number. So it's double 0 plus 1 = 1.

Answer: 12 x 123,456 = 1,481,472.

It looks complicated the way I've explained it, but I promise it's not!

I can see it. Do you use https://nostr.build to upload? Might help if you're having any trouble.

I could only see one. Then I realised it was from a previous post šŸ˜…

Working late has its benefits.

I like to take one of my kids out each weekend for a treat. This week it was my eldest son's turn, and his request was for wagyu. First time for him, second for me.

We found a delicious Korean BBQ place, we will definitely be going back 🤤

#Homeschooling / #unschooling is the way. My seven year old would have likely been diagnosed with ADHD if his "teachers" got their way.

He has gone from illiterate to reading novels, and showing real talent for mathematics. He is completely self taught except when I occasionally show him some fun tricks with numbers like in the picture.

And the most important part is how much happier he is.
