How do you write numbers in expanded notation?
- Writing a number in expanded form means to show the value of each digit in the number.
- We start in the ones column.
- 9 is simply 9 ones so we just write 9.
- 4 is in the tens column so is worth 40.
- 1 is in the hundreds column so is worth 100.
- We write 149 in expanded form as 100 + 40 + 9.
- We write the values as a sum.

- Move the decimal point so that you have a number that is between 1 and 10.
- Count the number of decimal places moved in Step 1 .
- Write as a product of the number (found in Step 1) and 10 raised to the power of the count (found in Step 2).

Expanded notation in primary school
Sometimes teachers will talk about an 'expanded method' for working out a number sentence. This means partitioning a number before carrying out an addition or multiplication. For example:
Expanded notation for multiplication
The expanded method for multiplication could be writing the calculation out like this:
The Long Way
Picture yourself blowing up a balloon. What happens when you blow air in? It expands - it gets bigger. Now look at this: 300 + 40 + 7. You remember what this is, right? It is the number 347 written in expanded notation - just a bigger form of the same number.
Dividing With Expanded Notation
As we just reviewed, expanded notation keeps a number's place value and helps us visualize exactly what the numbers represent. Solving long division problems with expanded notation is just a repeated series of steps that involves dividing, multiplying, and subtracting.
Follow the Pattern
Remember this pattern: 'Divide, Multiply, Subtract' (÷) (x) (-) and you will do just fine. Let's think about this pattern as we go through the first example.
Three Digit Dividend
Let's take our 'Divide, Multiply, Subtract' pattern and try a division problem with a three digit dividend.
What is Multiplication?
The process of finding out the product between two or more numbers is called multiplication. The result thus obtained is called the product. Suppose, you bought 6 pens on one day and 6 pens on the next day. Total pens you bought are now 2 times 6 or 6 + 6 = 12.
Methods of multiplication
There are two methods of multiplying the numbers, namely the expanded notation method and the column method.
Long Multiplication
Long multiplication is similar to the column method except for the fact that here we multiply the larger numbers. This method is used when the multiplicand is greater than 9, i.e. the multiplicand is more than a one-digit number. This method involves the following steps –
Properties of Multiplication
Commutative Property states that when an operation is performed on two numbers, the order in which the numbers are placed does not matter. This means that if one number is multiplied with the other, it does not matter which number is marked as the multiplier and which number is marked as the multiplicand.
Multiplication in Real Life
We use multiplication in solving our day to day problems. Let us see some of the examples.
