I was asked the above question in this comment. I understand many students are facing the challenge in sketching distance-time graph given speed-time and vice versa. I have prepared 2 videos to share with you what I taught my students in my weekly coaching programme.
Video 1: Convert Speed-time graph to Distance-time graph.

3 months ago in January 2010, I did a simple survey to find out if readers of singaporeolevelmaths.com like what they’re reading on the website.I would like to thank subscribers who have responded to it.
Here’s the outcome:
I’m really touched by the survey results: almost 90% of the respondents like the content I have been writing for singaporeolevelmaths.com since 2007.
As this blog is meant for
Students from all over the world to pick up Math ‘shortcuts’, tips and problem solving strategies
Parents to be updated of the latest educational news
Educators to find out more teaching resources and methodologies to enhance their teaching, tutoring and coaching
I would like to find out specifically what students want me to write on in the upcoming months.This allows me to find out what you want to read about as a reader and allow you to benefit from my sharing.

During this period of time, a Singapore website is ranked high in the search engines. Do you know which website? With the deadline for filing tax to be on 15 April, many people are flocking to IRAS to do their last minute e-file.
For a 15 – 16 years old teenager, he gets transformed into a tax officer (though a really entry level one) where he learns the basic in calculating the income tax.
Let’s use the following question as an example,
Chargeable income = Gross annual income (inclusive other income streams like rental etc) minus reliefs
Mr Tan income is only from his work, so gross annual income
= 3250 x 12 = 39 000
Total reliefts
=3000 + 2000 + 2000 x 2 + 7800 + 600 + 2/100 x 39 000
=18 180
Chargeable Income = 39 000 – 18 180 = 20 820
We can refer to the table of tax rate to calculate the amount of income tax Mr Tan has to pay.
We choose the one circled in red:
First 20 000: $0
Next 820 (20 820 – 20 000): 3.5/100 x 820 = $28.70
I hope you find this post useful. Leave me your comment on Income Tax. Have you learnt the concept? Do you know it’s under the topic of ‘Everyday Math’?
