nothing it stays the same. For example 21 + 10 = 31
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!
increase by one in tens place
13.899758 Remember for decimal digits, the nomenclature(naming system). From the decimal digit to the right. tenths (8) hundredths (9) thousandths (9) tens of thousandths (7) hundreds of thousandths (5) millionths. (8) To select the nearest 'tens of thousanths' look at the next digits to the right (hundreds of thousandths). If it is five or greater add one to the tens of thousandths column. In this case it is '5' , so add '1' the tens of thousandths colum , which is 7 + 1 = 8 Hence the answer is 13.8998 Done!!!!
167 may be written as one hundred sixty-seven. A hyphen should always be used between the tens and units digits when writing out numbers, but never between the hundreds and tens digits.
97 is one example.
The tens increase by one while the ones decrease by one. For example 9,18,27, and so on.
To find the last but one digit in the product of the first 75 even natural numbers, we need to consider the units digit of each number. Since we are multiplying even numbers, the product will end in 0. Therefore, the last but one digit (tens digit) will depend on the multiplication of the tens digits of the numbers. The tens digit will be determined by the pattern of the tens digits of the even numbers being multiplied.
249 + 318 = 567
754 Piece of cake!

The likelihood is that they either increase or decrease by one but we can't say for sure without seeing the problem.
It means five lots of one hundred, add one lot of tens and then 3 units.
