npub1d5tlq55s0w5vr2truq2fz3d7c7jm06w4pzfn4w2c5qqm9mkd9mvq563ad4 (npub1d5t…3ad4) is it supposed to say "8+2+7"?
Which would equal 17, of course.
Common core math is supposed to make math in your head easier (I think), but it seems very odd if you learned the other way.
And I imagine it doesn't feed well into algebra.
