Here is a simpler method to find the product of 2 numbers close to 100 by just mind calculation

98 x 99

2

98 x 99

2 1

2 x 1 = 2 this will so 02 will be the last part of the answer

98-1 =97

99 -2 =97

this would be the first part of the answer so

98 x 99 =9702

5

5 2

98 - 5 = 93

so answer of 95 x 98 = 9310

**Example**1 : Suppose you want to know 98 x 99**Step****1**:98 is 2 short of 100 so put2 below 9898 x 99

2

**Step****2**: 99 is 1 short of 100 so put 1 below 9998 x 99

2 1

**Step****3**: Multiply the 2 numbers put below2 x 1 = 2 this will so 02 will be the last part of the answer

**Step****4**: Subtract diagonally98-1 =97

99 -2 =97

this would be the first part of the answer so

98 x 99 =9702

**Example 2**: 95 x 98**step 1**: 95 x 985

**step 2**: 95 x 985 2

**step 3**: 5 x 2 = 10**step 4**: 95 - 2 = 9398 - 5 = 93

so answer of 95 x 98 = 9310
