as many as needed to satisfy the accuracy needed.
You do by subtracting one from the previous number and adding 10 to the top number of the digits you are regrouping. Subtract those two digits and you should get your answer.
Adding whole numbers is the addition of decimals where the decimal part is zero; in both cases the digits are place value aligned meaning that the decimal points, which lies between the units (or ones) and tenths columns, are aligned - in the whole number the decimal point is "hiding" at the end.
Standard algorithm is when you take two digits or decimals and you put the digit or decimal with the greater value on top and the digit or decimal with the least value on the bottom and you contrast the digits/decimals to see if it greater than, less than,or equal to.
They are decimal representations of numbers which stop after a finite number of digits (or continue with an infinite string of 0s).
There is an infinite amount of decimals between 0.1 and 0.11. Write "0.10", and then add any digit or digits you like - the result will be between those two.
Adding and subtracting with decimals primarily involves aligning the decimal points and performing the operation, ensuring that the digits are correctly placed in relation to the decimal. In contrast, multiplying with decimals requires multiplying the numbers as if they were whole numbers, then counting the total number of decimal places in both factors to place the decimal point in the product accurately. While addition and subtraction focus on the positional value of the digits, multiplication also incorporates the overall scale of the numbers involved.
The simplest way is to line up the numbers so that their decimal points are aligned, and corresponding digits are also aligned according to their place value.

When adding or subtracting two decimals, the first thing you must do is align the decimal points of the numbers. This ensures that the digits are correctly positioned according to their place values (ones, tenths, hundredths, etc.). After aligning the decimal points, you can proceed with the addition or subtraction as you would with whole numbers. Finally, remember to place the decimal point in the result directly below the aligned decimal points.

A zero placeholder is necessary when adding or subtracting decimals to ensure that numbers are aligned correctly according to their place values. For example, if you have 2.5 and 1.75, it helps to write 2.50 to clearly align the tenths and hundredths places. This alignment prevents errors in calculations by maintaining the proper value of each digit, allowing for accurate addition or subtraction. Without the placeholder, it could be easy to miscalculate by misaligning the digits.
The difference of two decimals is an integer when the two decimals have the same number of digits after the decimal point, and their fractional parts cancel out perfectly. For example, subtracting 2.50 from 5.50 results in an integer (3.00) because both decimals have two digits after the decimal point. If the decimal parts align such that their difference results in a whole number, the outcome will be an integer.
Because when adding or subtracting, the operations must take account of the place values of individual digits in the numbers. When multiplying, only the overall order of magnitudes are relevant for placing the decimal point in the product.
