Question

GENERAL FORM OF TWO DIGIT NUMBER​

Answer 1

Answer:

Numbers can be written in general form. Thus, a two digit number ab will be written as ab = 10a + b. The sum of a 2-digit number and the number obtained by interchanging its digits is always divisible by 11.

Answer 2

Answer:

The general representation of a number is as follows:

For a two-digit number say AB = A × 10 + B × 1

For example, 95 = 90 + 5 = 9 × 10 + 5 × 1

For a three-digit number says ABC

= A × 100 + B × 10 + C × 1

= 100 A + 10 B + C

For example, 123 = 100 + 20 + 3

= 1 × 100 + 2 × 10 + 3 × 1
