That’s pretty good.

Brilliant, that’s the loudest I’ve laughed in recent memory.

Explain how you got your answer.
“Math”

[HiTech RedNeck]

This “could” be explained in algebraic notation, and it might not be all that bad a way to juggle numbers in one’s head. On paper, “common carrying” beats the pants off of “common core.”

Who would be so stupid as to go through that manipulation to add those two numbers.

Here's a visual on the stupidity. Put a pile of 27 pennies and a pile of 16 pennies on a table. Now go through those manipulations. Absolutely no logic.

A 5th grader has to be "taught" to do simple addition and subtraction? In my day we were past that level in 2nd Grade.

O stranger, tell the Lacedaemonians that we lie here, obedient to their command.

Listen, O isles, unto me; and hearken, ye people, from far; The LORD hath called me from the womb; from the bowels of my mother hath he made mention of my name. (Isaiah 49:1 KJV)

Let’s see: 26 + 17 + ??

6 and 6 are 12. Plus one is 13.

2 and 1 are 3. Plus the carried one from the 13 make 4.

The answer is 43. Took about 5 seconds to do in my head, even without being able to add 6 and 7 directly.

I’m not sure how, exactly, that “common core” method is supposed to come up with an answer.

[Yardstick]

Reminds me of the shortcuts I use to do math quicker. The catch is that I can make shortcuts because I understand the underlying basic math. If this is advanced material taught after the basics have been learned then I don’t have a problem with it. If it’s being taught instead of the basics then that’s a problem.

Wooo-hooo! My husband, who is an aeronautical engineer (and a retired Naval aviator), LOVED this intelligent young man’s answer.

“That’s real retarded, Sir...”

[JoeFromSidney]

When I'm doing math in my head, I use a lot of tricks like the one here, breaking numbers into parts and dealing with the parts. However, this makes no sense at all when teaching math to grade schoolers. They need to be taught the basic methods of adding and subtracting, carrying, etc. Once they have those down pat, they can start using these tricks when they have to do mental arithmetic.

FReep Mail me if you want on, or off, this Wisconsin interest jping list.

If that word was important, it would have been included in the post.

As it is, I think you’re just a troll looking for clicks to your blog.

[ClearBlueSky]

Perhaps those who support this convoluted idiocy would like their SALARIES added up that way? What`s a few number less when it comes to real money?

[Fresh Wind]

Push 2
Push 6
Push Enter
Push 1
Push 7
Push +

LOL! Good for him. MATH!

I love it.

[FrdmLvr]

Well actually it’s not math but simple arithmetic, but who’s counting, right? (pun intended)

[UCANSEE2]

Oh... I remember the good ole' days when we had these....
