Assuming that "adds up to" means "its digits add up to" 888
increase by one in tens place
Add the digits together. The sum of the digits of 23 is 5.
27 plus 81 is 108. This is because if you add the ones place, which would be the 7 of 27 and the 1 of 81 you get 8, which becomes the answer's one place. You then do the same thing except with the tens place, which are the numbers 2 and 8. Since this gives you 10, a double digit number, the 0 stays in the tens place and the 1 carries over to the hundreds place. So if you put the 8 in the ones place, 0 in the tens place, and 1 in the hundreds place, you get the number 108.
They add up to 9
21 + 75 = ? Add the digits at ones place: 1 + 5 = 6 Add the digits at tens place: 2 + 7 = 9 So, the answer is 96.

Method 1:Count 13 more numbers after 13. But this method is suitable for only small numbers.Method 2:Steps of addition of two or more numbers:1 - Add the digits of ones place and if the result is greater than 10 then then only 0 is written and 1 is taken as carry to the tens place. If result is less than 10 then the number is written.2 - Then we add the digits of tens place with carry if there is any and the same procedure is to be followed mentioned in the first step.Here the digit 3 is at ones place and 1 is at tens place in both numbers.Addition of 3 and 3 = 6Addition of 1 and 1 = 2The corresponding digits which we get on addition are written in the corresponding places.6 takes its place at ones place and 2 at tens place.The result so obtained is: 26.
To take the tens place and add it to the other tens
Look at the thousands digit;if it is 5 or more add 10,000 to the number; if not don't add anything Replace the thousands, hundreds, tens and units digits by 0s.
Make sure that you add units to units, tens to tens, hundreds to hundreds, and so on. Keep the digits which represent the numbers in the correct columns before you add.
Look at the tens digit. If it is 5 or more, add 100 to 9876. Then replace all the digits to the right of the hundreds digit (the tens and units digits) by zeros. The answer is therefore 9900
To find the answer, multiply 7 times the number in the ones place (3) to get 21. Place the 1 in the one's place in the answer and carry the 2 to the tens place. Multiply the 6 in the tens place by the 7 to get 42 and add the 2 that you carried to get 44. Place that in the answer. The answer is 441.
if you add the digits of the number such as 81 8+1=9 every time, the digits of the number will add up to 9
