There is a model method to this but it can be tedious.

Thanks!

Common question at P3 level if your child's school is known for setting difficult questions.

Sorry why -12 -12?

Let me show you the model before and after. Wait ah....

Ok thanks

When you move the 12 over to the upper deck, the child must also consider cutting the portion just below it. That is why you must subtract 12 twice.

Ah.... Oic thanks Slow brain

Thanks so much

No worries, and not slow lah! :) This concept involves internal transfer involving whole numbers. Many average-performing P5s are still struggling with this actually. If your child can get it at P3, he or she actually knows more than many others in the cohort. ;)

Nowadays parents gotta learn first before able to teach our kids. I'm trying to learn too... I try to copy those tough questions and see how you guys solve then I gv it to my gir. Is so different fm what I had learned.

Especially involving models I'm confuse not sure which to use.

We're here to help. And I think you're doing a good job. Press on! :)

Thanks Darryl. Are you a educator?

Yes, just a humble, low-profiled one. Do a pte msg if you have more queries.

Thanks Darryl if you dnt mind I keep bothering you. Hahaha and more to come. ;)

Ask Jeannie cher!
