Determine whether the exercise is correctly written or not.
Note that the decimal points are not written one below the other. They do not correspond.
Therefore, the exercise is not written correctly.
Not true
\( \text{0.6+0}.5= \)
Decimal points show place value positions! When they're aligned, you add same place values together - ones with ones, tenths with tenths, hundredths with hundredths.
You'll get the wrong answer! For example, if 3.05 + 53.2 isn't aligned properly, you might accidentally add 5 hundredths to 2 tenths instead of adding them correctly.
It helps! You can write 53.2 as 53.20 to match 3.05's two decimal places. This makes it easier to see that place values are properly aligned.
Look at your decimal points - they should form a perfect vertical line. If they're zigzagged or offset, your setup needs fixing before you add.
Yes! All decimal operations (addition, subtraction) require proper alignment. The decimal point in your answer goes directly below the others too.
