The smallest 5 digit integer is -99999. The largest 5 digit integer is 99999. The sum is therefore 0.
'Number' or 'digit'.
1 is a single digit, 0 is the absence of a digit.
The negative three-digit number with the least value is -999.
Guess a positive single digit integer
The first number must be a nonzero single-digit integer. The exponent must be an integer.
312 is not a sequence: it is a single 3 digit integer and one number cannot define a sequence.

The smallest three digit integer is 100
The smallest 5 digit integer is -99999. The largest 5 digit integer is 99999. The sum is therefore 0.
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.
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 ).
The unit digit of a number is the digit in the ones place, which is the integer part of the number. In the case of 12.04, the integer part is 12, and the unit digit is 2. Therefore, the value of the unit digit in 12.04 is 2.
A decimal number can be an integer. All that decimal means is that the place value of each digit is ten times that of the digit to its right.
In normalized scientific notation all numbers are written in the form a x 10^b (a times ten raised to the power of b) where a is a nonzero single-digit integer and b is an integer.
