- Successor of 10199 is ———————-
- State the property used here: 43 + 52 = 52 + 43

Answer the following: - Write the whole number whose successor is 18900.
- Write the whole number whose predecessor is 9999.
- State the property in each case:

a) 21 + (34 + 23) = (21 + 34) + 23

b) 32 + 21 = 21 + 32

c) 24 x (20 + 5) = 24 x 20 + 24 x 5 - Find the value using suitable rearrangement: 25 x 679 x 4
- Find using distributive property: 235 x 102

Answers:

- Zero
- One
- Natural numbers
- Whole numbers
- Successor
- Predecessor
- Zero
- 999
- 10200
- Commutative property
- 18899
- 10000
- a) Associative property

b) Commutative property

c) Distributive property - 25 x 679 x 4 = (25 x 4) x 679 = 100 x 679 = 67900
- 235 x 102 = 235 x (100 + 2) = 235 x 100 + 235 x 2

= 23500 + 470 = 23970
