Place value is the value a digit has based on its position in a number. Face value is the digit itself, regardless of position. Example: in the number 5,472 — the digit 4 has a face value of 4 and a place value of 400 (since it is in the hundreds place).
Face value = the digit itself; it never changes with position.
Place value = digit × positional value (ones=1, tens=10, hundreds=100, ...).
In 5,472: face value of 4 is 4; place value of 4 is 400.
Place value of 0 is always 0, regardless of position.
Place value = Face value × Positional value.
Face Value: • The digit itself, regardless of where it appears. • Face value of 6 is always 6, in any number.
Place Value: • The value of a digit based on its position. • Place value = face value × positional value
Example: Number = 5,472
Digit → Position → Face Value → Place Value 5 → Thousands → 5 → 5 × 1000 = 5000 4 → Hundreds → 4 → 4 × 100 = 400 7 → Tens → 7 → 7 × 10 = 70 2 → Ones → 2 → 2 × 1 = 2
Note: The face value of 0 is 0; the place value of 0 is also always 0.
Position → Place Value Ones → 1 Tens → 10 Hundreds → 100 Thousands → 1,000 Ten Thousands → 10,000 Lakhs → 1,00,000 Ten Lakhs → 10,00,000 Crores → 1,00,00,000
Example: Number = 73,45,812
Digit → Place → Place Value 7 → Ten Lakhs → 70,00,000 3 → Lakhs → 3,00,000 4 → Ten Thousands → 40,000 5 → Thousands → 5,000 8 → Hundreds → 800 1 → Tens → 10 2 → Ones → 2
Sum = 73,45,812 ✓
Face Value: • Fixed — does not change with position • Face value of 7 is always 7 • Used to identify the digit
Place Value: • Varies — depends on position in the number • The digit 7 has place value 7 in ones, 70 in tens, 700 in hundreds, etc. • Used to determine the actual contribution of a digit to the number
Special case — digit 0: • Face value = 0 (always) • Place value = 0 (always, regardless of position)
Relationship: Place Value = Face Value × Positional Value For the digit 6 in the hundreds place: Place Value = 6 × 100 = 600 Face Value = 6
Face value is the digit itself (e.g., 4 always has face value 4). Place value depends on position (e.g., 4 in hundreds place has place value 400). Place value = face value × positional value.
7 is in the tens place. Place value = 7 × 10 = 70.
Face value of 6 is 6 (face value is always the digit itself, regardless of position).
The place value of 0 is always 0, regardless of its position in the number.

Learn the formula for the derivative of sin inverse x (arcsin x). Understand the step-by-step mathematical proof using implicit differentiation.
What is the Derivative of sin x?
d/dx(sin x) = cos x. Proof using first principles: lim(h→0)[sin(x+h)−sin(x)]/h = cos x. All trig derivatives covered.
