And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.

This is why you homeschool/fork over the coin for private school.
Hmmm. When I was studying physics at Uni, the head of the dept. was upset because so many students were way out of the ballpark when submitting problem assignments. It's like they were adding 2+2 and getting 1,631 or -512; it should have been obvious that something wasn't right. Some students were submitting work which seemed ludicrous to the instructors, the answers were so far off from what they expected to see.
As a result we all got additional work in estimating what an answer should be, and that may have been the point of this question. It's not asking what the correct answer is, but whether this answer is reasonable, something that could be expected; so this might be a problem in estimation instead of pure math.
Mind you, I'm not defending Common Core, that monstrosity needs to be abolished! But perhaps there's more to this than meets the eye!
It should've been written, "estimate and explain your answer." Student could've also rounded up to 105-30=75. Only 70 when rounded down. So by rounding both values would've been correct. But that's too easy. olds mo william
Uncle Sugar for you...
ReplyDeleteUncle Sugar for you...
ReplyDelete100 -30 = 70 is that a reasonable answer.
ReplyDeleteNo, but that's Common Core for you, because 100-30 is soooo much easier than 103-28.
DeleteHear that sound? That's the sound of millions of engineers' minds being snuffed out in a moment...
It's Wrong, it asked for an answer, not a rough estimate. Poor enigineers, I join Beans in mourning them!
DeleteApparently, that's good enough for grubbermint work, and precisely why we lose.
