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.
They add up to 9
24
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.

Multiplying a 2-digit number by a 1-digit number involves multiplying the digits in the ones and tens place and then adding the products. Similarly, multiplying a 3-digit number by a 1-digit number follows the same principle, where you multiply the digits in the ones, tens, and hundreds place and then add the products. The main difference is that in the latter case, you are dealing with three sets of digits to multiply and add, whereas in the former, you only have two sets of digits.
Well, isn't that just a happy little question! When you add tens to a number, the tens digit increases by one while the ones digit stays the same. It's like adding a little touch of sunshine to your number, making it just a bit bigger and brighter. Just remember to keep those digits happy and balanced as you add those tens!

To take the tens place and add it to the other tens
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.
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.
