### how to 9999*9997 in 5 secs with Base method

Procedure Do the tricks Find the near base divide into two sections  left side is cross sum and right side multiplication of two values for right side we need to take result number should be equal to the number of zeros in base For better knowing we will take simple Example 1) Solve 7*8? It is easy for this but in the point of large numbers it is useful Ans)    step by step  Finding the nearer base                              7       near base is 10                                8        near base is 10    Finding the Deviation from Base                              7         -3( it comes 10-7=  -3)                              8         -2 ( it comes 10-8= -2) Next step DO the the third step                              7          -3                              8         -2                    -----------------------------      Either (7+(-2) or (8+(-3)   |     multliply -3*-2( take result euqal to num of zeros in base)                             5     |     6           So ans is
