Subtraction with a lot of borrowing in different bases.
- Converting numbers between bases - A conversion calculator and table of example values to help understand other bases and change between them.
- How do you subtract numbers and borrow in base 8, base 4, and base 2?
- How do you subtract 45554 - 16365 in base 8?
- How do you subtract 10021 - 3223 base 4?
- How do you know how many to borrow when using different bases?
- How do you subtract 111011 - 11111 base 2?
- How do you subtract numbers in base 2 if you need to borrow?
This is the final of the 3-part series on adding and subtracting numbers in different bases. This lesson is about subtracting numbers with borrowing in other bases. Many good examples are shown with an abacus. This really helps students see clearly how this operation works.
What is this? I'm sorry, I can't learn like this. It would be nice if the video just got straight to the point rather than annoying me with this failed attempt at entertainment.
I love it! This video, and all videos by Perez, are awesome. As an adult learner, I really connected to his explanation and humor!
