Place value & Face value of number
The place value of a digit in any number is the value it holds to be at that position in the number.
In any number every digit has place & face value. We will learn it in detail.
The symbols or numerals in writing any number are called digits. We can use 0,1,2,3,4,5,6,7,8 & 9 symbols to form any number.
We can use these digits to make 2, 4 or multi digits number.
The face value of a digit for any place in each number is the value of the digit itself. This value does not change wherever it placed in the number.
E.g. 45 – Here face value of 4 is 4 & in 5467 also face value is remain 4.
But this is not true for place value, it is depending upon the position of the digit in given number.
