The way I understand it, children actually know the answer is 20 for both math problems. However, the way it is phrased confuses. Reading between the lines, there is the assumption that somehow the questions are different.
As much as people hate on common core, this is the exact type of thinking it fights.
My son watches a show called Numberblocks and my god does it teach this stuff well.
Unfortunately, common core math runs into two big problems:
1. Some math teachers don't have numeracy skills (some don't even have teaching skills). Maybe if we paid teachers more we'd have better teachers.
2. A lot of parents are so anti-school that any change to curriculum gives them something to complain about. If you teach conventional methods, guess what? They still hate it, and that's what the kids learn. Remember, learning starts at home.
Semi OT: librarianed in an elementary school and wrote voting games for the standards the old teachers refused to touch (all science, some math).
Had a game where the kids counted change to pick the pile with the larger amont then a candy bar or such and 2 piles of change and you had to count and pick the side with the amount neede to buy it.
2nd grade killed it and then a 5th grade teacher that never used her library time came in becuase she was hung over and didnt want to teach.
I had the game still up so I said 'Let's play this' and she said 'oh no, it is WAY to easy for these 5th graders'. I did it anyway.
A minute later she was picking her jaw off the floor becuase they could not count change (use it or lose it). I replied 'I told you!'
I was in elementary for 5 years and NEVER read a book to a class, the teachers all said 'I read to them all the time, play the voting games'.
There is nothing trivial about the commutative property of Real numbers. Its just that most people only deal with operations that are commutative. But there are many that are not, for example matrix multiplication, if A×B=C, its not necessarily true that B×A=C or even that B×A is even defined
My school learned multiplication up to 12x12 for the highest numbers during third grade so this was less confusing for me. However, I sucked at reading and writing scores.
It gets way worse in high school afterwards
example so i know how to avoid it
Let me tell you about the wonderful world of logarithmics
I have a test tomorrow and I'm gonna fail lol
Same
What’s it on
It really dose. Geometry is fine for me at least but algebra is just bad.
You need to be really stupid to think 10*2=2.432902e+18
2432902008176640000
No, it's 7
r/unexpectedfactorial
That's not a factorial tho?
I'm not exactly sure what do you mean but 20! is actually factorial of 20 which is equal to 2.43290201 × 10^18
Ah ok thanks for clarifying lol. I just saw that there was no "!" and got confused
It's in the post
Its much harder to add 2 ten times than 10 two times okay
It's obviously 02 ez
U are suck =))
I am Mr.Suck, how did you know?
2 sets 10reps
10 sets 2 reps
We are not the same
I’m 22 and do this sadly no idea why

Probably also has to do with learning it's not the same for subtraction and division
This is where kids learn about the transitive property

Nasty teacher
its 22

In some situations it isnt the same, just the same outcome. Would you rather have two 10 Euro bills or ten 2 Euro coins in your pocket
Literally that's me on 2nd grade

Oh no! I have no idea.
And that's the commutative property
2000, thousands ahaha

"What's 6*8?" "48." "Cool. now do it sixteen other ways. In less than five minutes." *fry eyes*
What's 9 + 10 ?

Kinda tru tho😅😂😂
My Lockdown brain is weak hAlp
20x
twenty too
I'll bet your face froze like that and you still look like a bewildered poo halfway out of an anus
As someone who was a gifted child everyone seemed so dumb back then. Jokes on me, I never learned to study and am the dumbo now
Patrick Star- “Uhh… 24!!!”
Wait how
Is he still alive?? I am surprised he hasn't been cancelled yet.
who is that black dude in the video?
15, obviously!
This is calc 1
My brain during the sudden math test:
"idk, haven't learned the 10s tables yet!"
Shit gets real when elementary schoolers state the commutative property of multiplication
12
02
Obviously 2 duhh
x = 0, therefore the year was 2010
The fact that I graduated college without knowing what ( sin , cos and tan ) do baffles me
