Q&A - P4 Math

[millan]

Hi ,

Just one week before my dd 's maths, I just realized that she is using the traditional method of doing multiplication . For eg, 186* 24, we will do 4186 then 20186, but she does by 624+8024+100* 24, mathematically both are correct, qn is am I correct to ask her to change? By doing 2nd method, u need to plus 3 rows and prone to summation mistake but she said she get used to it. Need advice if I shld force her to change. Thks

Hi millan,


Since it is only 1 week to her exam. I would not encourage u to change her method which she is used to it. Else it may cause her to be confused and more pro to mistake. Maybe try to convert her during the sch holidays if u wish to?

Hi

Your question is pretty similar to this one.

Weichong and Rama collect stamps. If Rama gives Weichong 15 stamps, he will have the same number of stamps as Weichong. If Weichong gives 15 stamps, he will have 1/2 as many stamps as Rama. How many stamps does each boy have?

Using similar approach as shown by Chamonix, you should be able to solve your question.

This is a question on “double if”. The ‘if” in the statement signifies that the scenario doesn’t actually happen.

If Vera gives Bala 2 stickers, he will have the same number of stickers as Vera.This means Vera has 4 more stickers than Bala.

If Bala gives Vera 2 stickers, Vera will have 5 times as many stickers as Bala.
Vera would have 8 more stickers than Bala.

4 units ----- 8 stickers
1 unit ----- 2 stickers.

Vera ----- 8 stickers
Bala ----- 4 stickers.

Best wishes
