Let's say you are baking cookies 🍪 and need to combine 2.35 cups of flour with 1.7 cups of sugar. Here’s how to add these decimals:

Align the decimal points:

`2.35`

+ 1.70Add the digits starting from the right:

`2.35`

+ 1.70

------

4.05

So, you need a total of 4.05 cups of ingredients.

**Example: Subtracting Decimals**

Now, imagine you have a ribbon 🎀 that is 5.8 meters long and you cut off 2.45 meters for a project. Here’s how to subtract these decimals:

Align the decimal points:

`5.80`

- 2.45

------

3.35

After the cut, you have 3.35 meters of ribbon left.

These simple steps can make adding and subtracting decimals easy, ensuring you get accurate results in everyday situations!
