someone needs to remake B5 with current CGI or just animated spaceships. I have such fond memories of how it all played out but I can't get through more than a few episodes for how terrible the CGI has aged.

You always know the right things to say to me during your time of the month. Luh you bubbee!
On an unrelated note to the forum troll : Anyone in Virginia know more about that Oil Spill in Lynchburg? Did it travel much further down the river?

What the shit, are they teaching rounding wrong!?
It should be:
354 + 291 = 645
400 + 300 = 700
Why would you teach a method of estimation that changes 291 into 200 instead of 300? It doesn't even simplify the concept of rounding for learning purposes since they have to learn the phrase "front-end estimation" and doing it right gives a wrong answer.

All these ignorant posts about that math problem, and people wonder why we are so far behind the world in math and science. It's a very simple teaching tool. Considering the math capability of your average American adult, you should be all for anything that works as a quick check on your arithmetic skills.
They're not teaching rounding, they're teaching estimation. Where rounding allows for an error of +/- 100, estimation (via truncation) is an error of +(0-198). So as long as the estimation is within 200, it's reasonable.
Not sure I agree with the value in actual use, but common core is about understanding abstract concepts, not efficiency.
Edit: Error for 3 digit estimation.
