We will solve addition and subtraction operations of decimal numbers in vertical form, always keeping in mind the following rules:
• All the rules that are applicable to the addition and subtraction of whole numbers also apply to decimal numbers.
• The decimal points must always be aligned one under the other.
• Numbers must be written in an orderly manner - both to the right of the decimal point and to its left (tenths under tenths, hundredths under hundredths, and so on)
Determine whether the exercise is correctly written or not.

Solve the following exercise and circle the appropriate answer:
Determine whether the exercise is correctly written or not.
The position of the decimal point corresponds..
Let's fill in the zeros in the empty space as follows:
We should note that the decimal points are written one below the other.
Therefore, the exercise is written in the appropriate form.
True
Determine whether the exercise is correctly written or not.
The position of the decimal point corresponds.
Let's fill in the zeros in the empty space as follows:
Note that the decimal points are written one below the other
Therefore, the exercise is written in the correct form
True
Determine whether the exercise is correctly written or not.
The position of the decimal point corresponds.
La posición del punto decimal coincide.
Note that the decimal points are not written one below the other.
Therefore, the exercise is not written correctly.
Not true
Determine whether the exercise is correctly written or not.
The position of the decimal point corresponds.
Note that the decimal points are not written one below the other.
Therefore, the exercise is not written correctly.
Not true
Solve the following exercise and circle the appropriate answer:
Let's solve the exercise in order:
We'll subtract the tenths after the decimal point:
Finally, we'll subtract the whole numbers before the decimal point accordingly:
And we get:
10.1
\( 8.5+5.2+8.4= \)
\( 10.1x+5.2x+2.4x= \)
\( 0.75+0.35= \)
Determine whether the exercise is correctly written or not.
The position of the decimal point corresponds.
Circle the correct answer to the following exercise:
We will break down each of the factors in the exercise into a whole number and its remainder.
We get:
Now we'll combine only the whole numbers:
Now we'll calculate the remainder:
And now we'll get the exercise:
22.1
We will factor each of the terms in the exercise into a whole number and its remainder.
We get:
Now we'll combine only the whole numbers:
Now we'll calculate the remainder:
And now we'll get the exercise:
