Example (i): 8,964,052 — In International system -
Place |Millions |Hundred {Ten Thousands |Hundreds |Tens |Ones
value thousands |thousands
Value |8,000, |900,000 /|60,000 5,000 0 50 = |2
of 000
digit
We can add the values of the digits to get the number.
8,000,000 + 900,000 + 60,000 + 5,000 + 50+ 2 = 8,965,052
Example (ii): 3,192,611 -
Solution: In International system 3,192,611 can be written in the expanded form as
3,000,000 + 100,000 + 90,000 + 2,000 + 600 + 10+ 1
Example (iii): 257,400 -
Solution: In International system 257,400 can be written in the expanded form as
200,000 + 50,000 + 7,000 + 400
e Standard Form:
We begin with expanded form and change it to the way we normally write numbers.
For example, 3 x 1,000 +5x100 + 7x10+4x1 can be changed to 3 thousands
and 5 hundreds and 7 tens and 4 ones. This becomes: 3000 + 500 + 70+ 4.
After doing the addition and we get 3574 (the standard form).
Example (i): 20,000.+ 7,000 + 400+ 20+ 2
Solution: 27,422
Example (ii): 700,000 + 60,000 + 20+ 9
Solution: 760,029
No value is given for the thousands and hundreds place, so we write zeros in these
two places.
Example (iii); 50,000 + 300 + 90 + 1
Solution: 50,391
No value is given for the thousands, so we write zeros in this place.
