Properties of Addition

1. When 0 is added to a number, the sum is the number itself. (e.g., \(51 + 0 = 51\), \(94 + 0 = 94\))

2. When 1 is added to a number, the sum is the successor of the given number. (e.g., \(39 + 1 = 40\), \(55 + 1 = 56\))

Ex 2.9

Question Fill in the blanks:
(a) \(14 + 0 = \_\_\_\_\)
(b) \(21 + 1 = \_\_\_\_\)
(c) \(54 + 1 = \_\_\_\_\)
(d) \(84 + 0 = \_\_\_\_\)
Answer:
(a) 14
(b) 22
(c) 55
(d) 84
In simple words: Adding zero leaves the number unchanged; adding one gives the next number.

Exam Tip: Apply addition properties directly without full column calculation.
