Question

what is the general form of 75 and 356
​

Answer 1

Answer:

Any two digit number ab made of digits a and b can be written as

ab = 10 * a + b = 10a + b

ba = 10 * b + a = 10b + a

This is known as the generalized form of the number.

Ex: 76 = 7 * 10 + 6

67 = 6 * 10 + 7

Again, any three digit number abc made of digits a, b and c can be written as

abc = 100 * a + 10 * b + c = 100a + 10b + c

cab = 100 * c + 10 * a + b = 100c + 10a + b

bca = 100 * b + 10 * c + a = 100b + 10c + a

Ex: 356 = 100 * 3 + 10 * 5 + 6

635 = 6 * 100 + 3 * 10 + 5

563 = 5 * 100 + 6 * 10 + a

In the same way we can write any number in general form having any number of digits.
