Whole numbers are closed under addition and also under multiplication.

Whole numbers are not closed under subtraction and under division.

Division of a whole number by 0 is not defined.

Addition and multiplication are commutative for whole numbers.

### Write the next three natural numbers after 10999.

10,999 + 1 = 11,000 11,000 + 1 = 11,001 11,001 + 1 = 11,002

### Write the three whole numbers occurring just before 10001.

10,001 – 1 = 10,000 10,000 – 1 = 9,999 9,999 – 1 = 9,998

### Write the successor of 2440701.

Successor of 2440701 is 2440701 + 1 = 2440702.

### Write the predecessor of 94.

The predecessor of 94 is 94 – 1 = 93.

### If the product of two whole numbers is zero, can we say that one or both of them will be zero? Justify through examples.

Yes, if we multiply any number with zero the resultant product will be zero. Examples: 2 x 0 = 0, 5 x 0 = 0, 9 x 0 = 0 If both numbers are zero, then the result also be zero. 0 x 0 = 0

### If the product of two whole number is 1, can we say that one or both of them will be 1? Justify through examples.

If only one number be 1 then the product cannot be 1. Examples: 5 x 1 = 5, 4 x 1 = 4, 8 x 1 = 8 If both number are 1, then the product is 1 1 x 1 = 1
