Time - Applying Time

You have learned about Time.

Today, we will learn how to apply Time in our daily lives.

There are a few things you must know about Time:

1 Day = 24 Hours
* Notice the short needle will rotate from 0 to 12 for 2 rounds to reach 24 Hours

1 Hour = 60 Minutes
* The long needle will rotate from 0 to 12 for 1 round to reach 60 Minutes

1 Minute = 60 Seconds
* The red needle will rotate from 0 to 12 for 1 round to reach 60 Seconds


To apply Time in our daily lives, here is an example:
Kamal got onto a bus ride from his house to school at 6.50 o'clock. The journey took 20 minutes. What time Kamal reached the school?

     06 50
+   00 20
     06 70 - BUT 1 Hour = 60 Minutes
So: 07 10 - 70 Minutes - 60 Minutes = 10 Minutes

Answer: Kamal reached the school at 7.10 o'clock.

If Raju went into the shop at 9.55 and came out 10.05, how long was he in the shop?

     10 05
-    09 55
     00 10 - 1 Hour = 60 Minutes

Step by step answer:
     09 65
-    09 55
     00 10

Answer: Raju was in the shop for 10 minutes.

Remember the lesson well. Thank you.

Time - Introduction

Greetings. Today, we will learn about Time.

Time is a measuring system used to:
1) Sequence events (Past events, Present events, Future events)
2) Compare durations of events
3) Compare the intervals between 2 or more events


Look at the clock below:

The time shown in the above can be written as:
1) Fifteen minutes past one or;
2) One fifteen
3) 1.45 (in numbers)

Now you try to write the examples below:

We will learn more about time in the next posting. Thank you.

Money

Today's topic is Money

Our currency is Malaysian Ringgit (in English) or "Ringgit Malaysia" (in Bahasa Melayu).
Our coins are cents (in English) or "sen" (in Bahasa Melayu).

These are the samples of our money:

RM 1.00


RM 2.00


RM 5.00




RM 10.00


RM 50.00


RM 100.00


As for our coins, they are as follows:

From left:
1 cent (RM 0.01), 5 cents (RM 0.05), 10 cents (RM 0.10), 20 cents (RM 0.20) and 50 cents (RM 0.50)


To represent the value of RM 51.25 in RM and cents, they consist of:

1 X RM 50 note
1 X RM 1 note
1 X 20 cents
1 X 5 cents


To represent the value of RM 78.68 in RM and cents, they consist of:


1 X RM 50 note
2 X RM 10 note
1 X RM 5 note
3 X RM 1 note
1 X 50 cents
1 X 10 cents
1 X 5 cents
3 X 1 cent

Thank you.

Mathematics - Division ( 8 ÷ 2 = 4 )

Division is the fourth basics in mathematics.

How do you describe Division?

Imagine..
if c times b equals a, written:

c X b = a

where b is not 0, then a divided by b equals c, written:

 a ÷ b = c

a  = c
b

If a = 6, b = 3, c = ?
We have:

6  = c
3

c = 2 because:

2 X 3 = 6

In the above expression, a is called the dividend, b the divisor & c the quotient

The symbol of Division is:

Division can be illustrated as:

Thank you. We will move on to the next topic in my next posting.

Mathematics - Multiplication ( 2 x 3 = 6 )

Multiplication is another basics of mathematics. What is Multiplication?

Multiplication is the scaling one number by another. 

For example, 3 multiplied by 4 (often said as "3 times 4") can be calculated by adding 4 copies of 3 together:

3 X 4 = 3 + 3 + 3 + 3 = 12
3 X 4 = 12

Here 3 and 4 are the "factors" and 12 is the "product".

The symbol of Multiplication is:

( Often spelled as 'times' )


Here are the tables of Multiplication:

Now you try:
Imagine you have a bag of 3 stones

If you multiply ( X ) that bag with 4 times, how many stones would you have?

(After multiplication, you would have 4 bags)

Now you will have 4 bags with 3 stones in each bag.
So, after multiplication, you now have a total of 12 stones.

Mathematics - Subtraction ( 3 - 1 = 2 )

Subtraction is the second basics of mathematics. Subtraction is: A collection, take away (subtract) by a certain number of objects.

It's sign is Minus.

For example:

Five minus two equal to three
5 - 2 = 3

This can be shown in the picture on left:
There are 5 apples
Two apples are taken (marked with 'X')
So, we now have 3 apples






Now you try:
Look at the number of fruits in the picture below and write the numbers into the empty lines

Remember:

Subtraction is taking away a certain numbers from a given number.

Mathematics - Addition ( 1 + 1 = 2 )

It's a pleasure to write again. There are 4 basics in Mathematics:

English: Addition ( + ) / Bahasa Melayu: Penambahan ( + )
English: Subtraction ( - ) / Bahasa Melayu: Penolakan ( - )
English: Multiplication ( x ) / Bahasa Melayu: Pendaraban ( x )
English: Division ( ÷ ) / Bahasa Melayu: Pembahagian ( ÷ )

Today, we start with Addition

Addition is combining two collections of objects / numbers into one larger collection.

 
Below are the examples:

Remember:
Addition = Combining two collections of objects / numbers into one larger collection.
