Lesson 3: Subtracting decimals (hundredths)

# 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.

• 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.
• 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.
• Why he think that we don’t know how to subtract?
• At I think Sal should have put parentheses to make it more understandable because of p-e-m-d-a-s. After he subtracted, the next thing that comes in the equation is addition but the he skips the addition and goes straight to subtracting so I think he should have put parentheses on both of the subtracting for the equation. I mean- we might understand what he is doing but Im pretty sure the correct way is to put parentheses. (I put this on tips and thanks but am I correct?)
