We've learned that adding and subtracting decimal numbers, numbers with a decimal point, is just like adding and subtracting whole numbers. The only difference is that we line up the numbers according to the decimal point. For addition, it doesn't matter which number goes on the bottom. Click to see full answer

How do you add decimals in a sentence?
To add decimals, follow these steps: Write down the numbers, one under the other, with the decimal points lined up. Put in zeros so the numbers have the same length ( see below for why that is OK) Then add, using column addition, remembering to put the decimal point in the answer.
What are the similarities in the process of adding or subtracting decimal numbers?
Subtracting decimals uses the same setup as adding decimals: line up the decimal points, and then subtract. In cases where you are subtracting two decimals that extend to different place values, it often makes sense to add extra zeros to make the two numbers line up—this makes the subtraction a bit easier to follow.

How is understanding decimals similar to understanding whole numbers and fractions?
Both fractions and decimals are just two ways to represent numbers. Fractions are written in the form of p/q, where q≠0, while in decimals, the whole number part and fractional part are connected through a decimal point, for example, 0.5. Fractions and decimals represent the relationship of part by whole.

What is the difference between addition and subtraction?
The only difference is that we line up the numbers according to the decimal point. For addition, it doesn't matter which number goes on the bottom. For subtraction, the number we are subtracting goes on the bottom. We then work our way from the right to the left.
How to subtract 0.36 from 0.84?
Say we are subtracting 0.36 from 0.84, 0.84 - 0.36. We write the numbers stacked on top of each other with the 0.36 on the bottom. We don't need any 0 placeholders. We then proceed to subtract the digits starting from the right and working our way to the left. Just like when working with whole numbers, if the digit we are subtracting from is less than the digit we are subtracting, we then take 1 away from the digit to our left so that we can add 10 to the digit we are subtracting from.
How to add decimals?
For example, to add 12.3 to 0.81, we write the numbers stacked on top of each other, lining up the numbers according to the decimal point.
How to add 10 to a number?
For addition, if we get 10 or more after adding two digits, we then carry the number in the tens place over to the digit to the left. For subtraction, if the digit we are subtracting is more than the digit we are subtracting from, we take 1 from the digit to the left in the top number and add 10 to the current digit we are subtracting from.
How to write 324 + 23?
For 324 + 23, you write it so that the 4 is on top of the 3. Then the other numbers follow suit.
Can you write 0 as a placeholder?
Just like we can write 0s as placeholders when we add whole numbers, we can do the same thing when adding decimals. We notice that there is no number above the 1, so we can write a 0 there as a placeholder and to let us know that the value of this spot is 0. We then can proceed with the addition like we usually do. When we get to the decimal point, we also write the decimal point in our answer directly underneath.
What does a zero mean in decimals?
A zero is really saying "there is no value at this decimal place". In a number like 10, the zero is saying "no ones". In a number like 2.50 the zero is saying "no hundredths". So it is safe to take a number like 2.5 and make it 2.50 or 2.500 etc. But DON'T take 2.5 and make it 20.5, that is plain wrong. Question 1 Question 2 Question 3 Question 4 ...
Why do you put zeros in numbers?
