Lesson 12: Subtracting decimals

Subtraction strategies with hundredths

This video is all about subtracting decimals, specifically those in the hundredths place. It covers different strategies for subtraction, breaking down the process into manageable steps, and emphasizes the importance of understanding the concept behind the calculations.

• I don't get any of the lessons this guy explains
• example-0.69-0.35
Sal-break everything up then find the answer.
me-subtract 69 and 34 put a . then a 0.
boom which way do u do it:)
• You don't subtract 34, you subtract 0.35. And its 0.69. If you did that, your answer would be 350. Because you said put a 0.
• If you are able to do problems in your head, you may be exceptionally bright. But, it's important to do things on paper so you will have a grasp of each of the steps in the process. These steps may come into play later on when you are working on more difficult concepts.

Much of math is building one concept upon another. Sort of the same as one brick upon another in construction. Nobody would build a brick wall and leave out some of the bottom bricks (the basics). That would only lead to problems later.
• My Question is that how do you know which number goes on top while subtracting decimals.
• The bigger number goes on top.
• A 1st grader can probably solve this
• 0.69 - 0.34? That's easy. 0.35!
• I'm imagining that "bunch of solves" instead of flowers and imagine someone's giving you that "bunch"...
