## How do you add decimals step by step?

What are the Steps for Adding Decimals?

- Step 1: First of all, align the decimal numbers according to their place values.
- Step 2: Then, convert the decimal numbers to like decimals, if needed.
- Step 3: Finally, add the numbers and place the decimal point aligned with the given decimal points.

**How do you add and subtract decimals examples?**

14.5 − 8.7 = (14 + 0.5) − (8 + 0.7) = 14 + 0.5 − 8 − 0.7 = (14 − 8) + (0.5 − 0.7) = 6 − 0.2 = 5 + 1.0 − 0.2 = 5 + 0.8 = 5.8. Here the number 1 is taken from 6, to help for further subtraction. Also, the subtraction 1.0 – 0.2 is same as the subtraction 10 – 2 = 8. And a decimal is placed in the answer 0.8.

**How do you subtract decimals step by step?**

To subtract decimals, begin by writing the numbers in a column, with the decimal points aligned. If necessary, add zeroes as place holders to make sure there are values in each column. Subtract from right to left. Write the decimal point in the difference directly below the decimal point in the subtrahend.

### How do we solve problems involving addition and subtraction of decimals?

Step 1: Identify the important numbers and key words in the problem that will indicate the operation(s) you will perform. Step 3: Stack the values to perform the operation from Step 2. Add or subtract the decimal values by lining up the decimal point and using zeros as place holders if needed to get your final answer.

**What is the first step in adding or subtracting decimals?**

Step 1: Line up the numbers vertically so that the decimal points all lie on a vertical line. Step 2: Add extra zeros to the right of the number so that each number has the same number of digits to the right of the decimal place. Step 3: Subtract the numbers as you would whole numbers.

**Do you have to line up the decimals when subtracting?**

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 does place value help me subtract decimals?

**What are the 4 steps in solving word problems?**

Polya created his famous four-step process for problem solving, which is used all over to aid people in problem solving:

- Step 1: Understand the problem.
- Step 2: Devise a plan (translate).
- Step 3: Carry out the plan (solve).
- Step 4: Look back (check and interpret).

**How do we solve problems involving multiplication of decimals?**

To multiply decimals, first multiply as if there is no decimal. Next, count the number of digits after the decimal in each factor. Finally, put the same number of digits behind the decimal in the product.

## How is adding and subtracting decimals similar to adding and subtracting whole numbers?

Subtracting decimals, just like adding decimals, is similar to subtracting whole numbers. Just like adding decimals, the only difference is that we line up according to the decimal point instead of the last digit.
