Short Form

To write the short form of an expanded number, we write the face value of

each digit in the correct place.

Look at the given example.

H T O

100 + 20 + 8 = 1 2 8

The place value of 1 is 1 hundred.
So, we write 1 at the hundreds place.

The place value of 2 is 2 tens.
So, we write 2 at the tens place.

The place value of 8 is 8 ones.
So, we write 8 at the ones place.

Similarly, 100 + 6 = 106 and 100 + 80 + 6 = 186.

Top Tip
We can write a number in three diff erent forms.

Short form Word form/Number name Expanded form
174 One hundred seventy-four 100 + 70 + 4

9. Write the short form of the given numbers.

(a) 100 + 8 = _________ (b) 100 + 20 + 9 = _________

(c) 100 + 40 + 4 = _________ (d) 100 + 90 = _________

Before, After and Between

I am between 7 and 9.
• A number just before any number is one I am after 8.
I am before 8.
less than it.

• A number just after any number is one
more than it.

• A number between two numbers is in their middle.
