99
A two-digit positive integer ranges from 10 to 99. It consists of a tens digit and a units digit, with the tens digit being at least 1. Thus, there are a total of 90 two-digit positive integers.
10
The smallest two-digit negative integer is -10. It is the first number in the range of two-digit negative integers, which includes numbers from -10 to -99.
The greatest sum of two two-digit numbers occurs when you add the largest two-digit numbers together. The largest two-digit number is 99. Therefore, the greatest sum of two two-digit numbers is 99 + 99, which equals 198.
3,162.27766 is the square root of a smallest 8 digit number and thus the greatest integer having the greatest 7 digit square is 3,162. This is because the square of the next integer i. e. 3,163 is going to be an 8 digit number as discussed above. Thus, 3,162 is the required answer. 3162^2 = 9998244.

Let the three-digit integer be ( x ) and the two-digit integer be ( y ). According to the problem, ( x - y = 288 ), which implies ( x = y + 288 ). The digits used are 7, 8, 2, 3, and 0. After testing possible combinations, the solution is ( x = 782 ) and ( y = 494 ). Therefore, the sum of the three-digit integer ( x ) and the two-digit integer ( y ) is ( 782 + 494 = 1276 ).

99 ofcourse
94 is the greatest two-digit whole number that when rounded to the nearest ten rounds to a two-digit number.

The greatest 4 digit integer divisible by 3 (and therefore a multiple of 3) is 9999.
