Solve the following exercise:
Let's solve the following exercise in the correct order.
First, we'll proceed to subtract the tenths after the decimal point:
Then, we'll subtract the whole numbers before the decimal point accordingly:
We obtain the following result:
10.1
\( 2.6:0.1= \)
Lining up decimal points ensures you're subtracting the same place values! Tenths subtract from tenths, ones from ones, etc. Without proper alignment, you'll get the wrong answer.
You can add zeros to make them equal! For example, 12.0 and 12.00 are the same number. This makes the subtraction easier to see.
In vertical format, always subtract the bottom number from the top number. Start from the rightmost column and work left, just like with whole numbers.
Borrowing works the same way! You can borrow from the ones place to the tenths place, or from tenths to hundredths. The decimal point doesn't stop borrowing.
Use addition to check subtraction! Add your answer to the number you subtracted: . If you get the original number, you're correct!
