Compute (22343234532 X 22343234532)-(22343234533 X 22343234531).      

 

The final answer is 1     

 

Adding commas to make the numbers easier to read, we obtain    

 

(22,343,234,532 X 22,343,234,532) – (22,343,234,533 X 22,343,234,531).    

 

For convenence, allow N to stand for 22,343,234,532    

 

Now the expression becomes    [N • N]  –  ( [N + 1] • [N – 1] )

 

Multiply it out                               N2 – (N2 – 1)      

 

This equals                                                1

22343234532^2 = 499220129351957259024

22343234533 * 22343234531 = 499220129351957259023

 

SUBTRACT  one from the other and the answer is   1
