Question

what will be the sum of the smallest and the largest seven digits numbers?​

Answer 1

Answer:

As usual, you didn’t state if the numbers should be positive whole numbers, or negative numbers are included, etc. So I’ll answer assuming you mean positive whole numbers.

The largest 7 digit number is 9,999,999, and the smallest is 1,000,000. The sum is 10,999,999

Answer 2

Answer:

Hey!pls don't forget to brainlist my answer it's really needed for the badge:)...

Step-by-step explanation:

=>Let the 9 is greatest decimal digit, the greatest 7− digit number would begin with as many nines as possible.

Since there must be 3 different digits in the 7− digits number,

Let begin with five nines and fill the last two places with 8 and 7.

The smallest seven digit number is 1000000

But we need three different digits it will be 1000002

Now,

Let find their sum =9999987+1000002=10999989.
