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.
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.

by adding or subtracting the values of the digits in the front place
same number of significant digits
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.
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.

The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
It just means to make sure that you complete the operation and don't have any additional digits when you're done. For example, if you're adding 3.7 and 4.3, you can say the answer is 8, not 8.0.
