Question

Determine the product of the greatest number of four digits and the greatest number of three digits

Answer 1

Answer:

Step-by-step explanation:

Largest 3 digit number=999

Largest 2 digit number=99

So we have,

999*99

(1000–1)*99

Using distributive property it can be written as

1000*99–1*99

=99000–99

=98901

Answer 2

Greatest Number of 4 digits = 9999
Greatest Number of 3 Digits = 999
Product = 9999 x 999
= 9989001
