Find the product of the greatest 5 digit number and greatest 4 digital number by using the distributive property.
To do:
Find the product of the greatest 5 digit number and greatest 4 digital number by using the distributive property.
Solution:
Greatest 5 digit no. = $99999$
Greatest 4 digit no. = $9999$
Using distributive property:
$99999 \times 9999 = 99999 \times ( 10000-1 )$
Applying distributive property to right hand side becomes
$( 99999 \times 10000 ) - ( 99999 \times 1 )$
$999990000 - 99999$
Therefore, the product is $999890001$
