Standard Form of Numbers
The standard form or short form of a number is given by combining the face value of each digit at the correct place.
A three digit number consists of three digit. For example
The standard form of 200 + 30 + 4 is 234.
The place value of the digits are
For 200 the place value is 2 x 100 or 2 hundreds so 2 is placed at the hundreds position
For 30 the place value is 3 x 10 or 3 tens so 3 is placed at the tens position
For 4 the place value is 4 x 1 or 4 ones so 4 is placed at the ones position.
Hence
234 is three digit number where 2 is at hundreds place, 3 is at tens place and 4 is at ones.
Similarly the standard form 700 + 20 + 8 = 728.
