What is the maximum number that can be written? What can a maximum number be written?

> 101, so you can write up to 13 numbers.

odd number + one even number = even number, impossible;

11 odd numbers: 1+3+5+--21=121>101; No way.

9 odd numbers: 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 8 + 12 = 101 holds.

So you can write up to 9 odd numbers.

Even numbers: 2+4+6+--20=110>101 is not true.

Because 0 is also a natural number, there is.

So. A maximum of 9 even numbers can be written, a minimum of 1 odd number can be written, and a minimum of 1 even number can be written.

If you want to count as much as possible, make each number as small as possible, and start with 1.

1 2 3 4 5 6 7 8 9 1 0 11 12 13 and 91 Add 10 But add 10 and repeat it, so you can only change 13 to 23 So that there are 13 in total.

The odd number is 9:1 3 5 7 9 11 13 15 17 19, and their sum is 81, which is 20 short, and if you add the odd number, you can't make 101, so just change 19 to 39.

The same goes for even numbers. The odd and even numbers are at least 1: divided into 1+100 and each odd and even.

The counting units are 10, 10, 100, 100000, 10000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 Ten years, 100 years, 1,000 years.

Hello, the 5 numbers in front of 1000 are: look.

Rounding. Move the 3 small black squares in the first row down to the second row, and there will be a 2*5+1*5=15 small black squares.

Put the small black square between the four and five elements back to its original place, there are 2*3+1*3=9 small black squares, a total of 15+9=24 small black squares, so there are 5*10-24=26 small white squares.

There are 26 white rectangles and 24 gray rectangles.

When counting, use the method of spelling to count, the first white rectangle to spell a spell, can be spelled into two rows and six, indicating that there are 26 white rectangles, a total of 50, 50 minus 26 is the number of gray rectangles.

Puzzle pieces, one or two lines combined, four or five lines combined.

The gray ones have 20+5+9 34, and the white ones have 50-34 16

This is my answer.

Analysis: (1) The single digit is 0, the ten digit is 0+3=3, the hundred digit is 3+0=3, and this number is: 330.

2) The single digit is 1, the ten digit is 1+3=4, the hundred digit is 4+1=5, and this number is: 541.

3) The single digit is 2, the ten digit is 2+3=5, the hundredth digit is 2+5=7, and this number is: 752.

4) The single digit is 3, the ten digit is 3+3=6, the hundred digit is 6+3=9, and this number is: 963.

There are four numbers, and three conditions are met at the same time: the hundred digit cannot be greater than 9; The hundredth digit is the sum of the tens and single digits; The number of tens is 3 more than the number of numbers, so the number of eligible hundreds:

Assuming the number is xyz, then:

x=y+zy=z+3

Two-formula substitution obtains.

x=2z+3

The above numbers are all single digit integers, then.

When z is at 0, 1, 2, 3 x does not exceed 10, and the result is out:

This is my answer.

Analysis: (1) The single digit is 0, the ten digit is 0+3=3, the hundred digit is 3+0=3, and this number is: 330.

2) The single digit is 1, the ten digit is 1+3=4, the hundred digit is 4+1=5, and this number is: 541.

3) The single digit is 2, the number of ten beams is 2+3=5, the number of hundreds, 2+5=7, this number is: 752.

4) The single digit is 3, the rubber decimal number is 3+3=6, and the hundred-digit repentance number is 6+3=9, this number is: 963.
