Assuming that "adds up to" means "its digits add up to" 888
increase by one in tens place
The greatest number you can add to 457 without regrouping in any place is 42. This is because, when adding 42 to 457, the digits in each column (units, tens, and hundreds) do not exceed the value of 9, thereby avoiding any regrouping. Specifically, 457 + 42 equals 499, which maintains the digits within their respective places.
In the number 708, the digit 0 holds a place value of zero in the tens position. This means it does not contribute to the overall value of the number, as it represents "zero tens." Therefore, while the 0 is essential for indicating the number's structure, it does not add any value to the total. The value of 708 is determined solely by the digits 7 and 8, which represent 700 and 8, respectively.
Add the digits together. The sum of the digits of 23 is 5.
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.
455
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.
In the number 708, the digit 0 holds a place value of zero in the tens position. This means it does not contribute to the overall value of the number, as it represents "zero tens." Therefore, while the 0 is essential for indicating the number's structure, it does not add any value to the total. The value of 708 is determined solely by the digits 7 and 8, which represent 700 and 8, respectively.
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
