Solve the following exercise:
To avoid confusion in solving the exercise, we will first add the digit 0 to the number 12.0 as follows:
Now let's solve the exercise in order:
Let's add the hundreds after the decimal point:
Let's add the tenths after the decimal point:
Finally, let's add the whole numbers before the decimal point:
We'll add ten to the ones digit before the decimal point and get:
And we obtain the following:
41.31
Choose the correct writing form:
Adding the zero creates matching decimal places! When 12.0 becomes 12.00, you can easily line up with 29.31 and add column by column without confusion.
No problem! Just add zeros as placeholders to make them match. For example, 5.2 + 3.456 becomes 5.200 + 3.456 for easier addition.
While not always required, it's highly recommended for beginners! Writing zeros prevents mistakes and makes the addition process much clearer and more organized.
Easy! The decimal point in your answer goes in the same column as the decimal points in the numbers you're adding. Keep everything lined up vertically.
Start from the rightmost column (furthest right) and work your way left, just like with whole numbers. This follows the same pattern you already know!
