Tell me without calculator?

See a simple math problem. 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. What is the sum of the largest and the smallest two numbers, and the sum of 4 out of 10 digits? There can be two answers here. If the same digit can be used more than once, then the number two will be 9999 and 1000. And their sum is 10999 and minus 8999. But if there is a condition to not use it again and again, then the numbers will be 9876 and 1023. The sum and the sum of these will be 10899 and 8853 respectively.

See another easy math. 3 + 3 + 3 (5 + 7) * 0 =? The answer will be 6. Because, according to the arithmetic rules, first calculate the first bracket and multiply it by 3 and multiply the value of 0. Then its value will be 0. So there will be only 3 + 3 = 6.

Last Sunday's riddle answers:

The puzzle was like this: 'I used to write a number using 10 digits from 0 to 9. The number is 8146329507. This number has been written in such a way that there is a special feature hidden in it. Now, what do you think about that feature? '

Several have answered. As one wrote, the sum of the 2nd and 3rd, the 5th and the sixth and the 8th and the 9th digit is equal. This is a feature. Another such feature may be, the difference between 1st and 10th, 2nd and 9th, 3rd and 8th and 5th and 6th grade differences is the same. But the special characteristics I have thought of from a completely different point. If you observe it well, the number according to the pronunciation in Bengali: eight one four six three two nine five zero seven. The first letter of each digit is in the order of the Bengali alphabet. That is, first eight 'a', then one is 'a', then four 'f', ... ch, t, da, n, p, sh, s. The alphabet sequence is specially characterized by the number!
