I Really Don't Remember Math Being This Difficult

Base 10 mental math has been around for centuries. I was taught this in the 1st grade in 1952 albeit with a less complicated explanation... 6+7=13 10+20=30 30+13+43. I still do this mentally with up to 5 digit numbers....but prefer a calculator...which allows me think about more important things. LOL!

Reminds me of the old Tom Lehrer song:
Hooray for New Math - New-ew-ew Math
It won't do you a bit of good to review math
It's so simple - so very simple
That only a child can do it!

Dumb theory of teaching devised by Education Major who has never actually spoken to kids because they all have cooties.

Your explanation makes sense. I still don't know what the heck they're doing in that example.

26+7=(26+4)+3 so 33.
I used it to do math in my head very fast. 26+58=((26+4)+50)+4 or 30+50+4=84.
Using that method to teach to beginners is idiocy.
The problem is that many school administrative types aren't good at math, they remember how hard it was to learn so they're trying to make it <i>easier</i>.
So we have high school students who can't multiply 5*9 or add 36+87.
