Another primary school math question has left netizens puzzled, sparking a debate on social media about the correct order of solving sums and the importance of quantifiers in mathematical equations.

actually this is quite basic stuff. p1 term 3-4 should already know. 
I admit i often get mixed up with this in the past but after my kid went to p1. It's quite fundamental to being precise. 

Not sure what the fuss is about.

The acronymn is GET. Group x Each = Total

5 x 8 implies 5 families of 8 kg each.

If i mark my own kid, sure give zero lol.

A monkey gets 3 bananas in the morning and 4 bananas at night.

He not happy and complain to owner

So the owner agreed to give him 4 bananas in the morning and 3 at night.

Teachers are monkeys because they are ONLY happy with the second one and the first one is no good to them!

:D

If you cannot do - teach!

Ya, X is call 'times' in ang mo, so this is how i see it.

5 times 8 means 8 occurs five times. (8,8,8,8,8) = 40

8 times 5 means 5 occurs 8 times.(5,5,5,5,5,5,5,5)= 40

 

But when writing math equation they are the same. i.e. 5 x 8 = 8 x 5 like wise x.y=y.x

The teacher marked the kid wrong because he answered without stating the "kg" unit. Nothing new. 60 years ago, my maths teacher also marked my correct answer wrong for the same reason. Kerna called up and then told "if you don't put units then the answer is what? Durians?". I carried the lesson all my life and always put down units.

Back to this question. Without the units, if the kid had answered as 40,000. Then when marked wrong, kid will say is 40,000 grams or 40kg.

For completeness the kid should have written

5 kg x 8 = 40 kg

A bit hard for even the most pedantic teacher to mark wrong!

Unless the teacher see the model answer as 8 x 5 = 40 kg and thought that's not the same as 5 x 8 = 40 kg

Some teachers know less than kids!

I has so many examples where teachers were wrong but didn't admit it and insist they were right.

And people wonder why an idiot on the road is wrong and still want to argue its not their fault, its yours!

They learn from teachers lah!

Face more important right?

:D

Err... this is in all their basic textbooks from primary 1 onwards. In fact the very first lesson on multiplication, u should already see all the picture diagrams.

Order matters. It starts with basic stuff like this.

A 3*2 matrix is not the same as 2*3 matrix.

I know white cat, black cat both can catch the mouse. But these are just basic habits to build for later more advanced stuff. 

 

If the working didn't matter, then it will just be a open ended answer. And maybe get full mark or half mark. No units at the answer also definitely will get minus mark.

Honestly this kinda marking is nothing compared to Science short answer questions marking.

I paid lots to tutors. Tutor's money is hard earned. They have to teach boring subjects to uninterested kids yet still be nice and smiley. Day and night.  Don't know how come my kids come to tuition time got so much urine and poo. In 90 minutes Chinese tuition, can pee 3X and poo.

The only time that a x b is not equal to b x a is if

a and b are vectors and 

"x" is the vector cross operation
