This video explains a shortcut for converting between Binary and other bases that are powers of 2. Specifically, we convert between BasThe same shortcut applies between Binary, Octal, and Hexadecimal, as well as between Base 3 and Base 9.
The shortcut that is demonstrated works because 4 and 8 are powers of 2, and because 9 is a power of 3. It is a GREAT time saver when you have bases that are related in this way, one is a power of the other.
So glad that I came across your video. Back many moons ago when I was in high school, I had figured out this exact method while sitting in class, because I was certain that there was an easier way to convert bases other than creating algebraic formulas or complex division. Once I had figured out that the numerical bases could correlate with each other, I began working it out in my head without writing anything down. Personally, I thought it was genius because I loved math and puzzles. Unfortunately, as life happened, I stopped utilizing the technique and forgot how to do it. I remembered that I did it, but couldn't remember how it was done. So, thanks so much for jogging the brain juices.
Thank you so much for the help! very good explanation:)
Glad it helped!

" Two to the third power is actually eight. This works whenever you have bases that are power to each other"
This video was helpful.
Fantastic to hear!
really good explanation
👍🤩Thanks!
Thanks for saving me
Happy to help!
thank you
You're welcome! Thanks for watching!
what about decimal pts?
Good question. I have not looked at that.
converting form base 8 requires transitioning to base 10 1st to go to base 2, got it but does this mean that base 8 can be base anything ? ? ? ?
Yes! The different number bases are just different ways of representing the same values. The number 8 can be represented in any number base.
How do you convert back from base ten to wherever you started?
Hi! You multiply it a h digit by its place value and add the products. For example, if you have 123 in base 4, that’s (1x4^2)+(2x4^1)+(3x4^0)
@@MzMath so, in your example, the result was 43 in base 10. I'm not sure, how do I convert that into a base 4 or base 6? What you just described is a repeat of the video, going from base 4 to base 10, no?
Can you divide 100 by three with an alternative base?
Interesting question! Thanks for posting. Yes, you can in the sense that the number 100 in base 12 (for example) is actually the quantity 12^3 which is divisible by 3.

This video helped me having knowledge of other methods for converting between certain number bases. The video also educated me on the concept that the power of two is equivalent to the place value of two, and it also demonstrated how to convert the base with two on multiple occasions.

The video helped me understand the place value of 2 is the power of 2.. along with converting the base with 2 repeatedly

"What base 8 means is the place values are all powers of 8."
I am struggling with a lot of topic 5.3, I have spent all night watching RUclips videos trying to connect the dots between all the different bases and how to find the numbers. As soon as I feel I understand one way, the next question in our assignment is completely different.
Hi Angela! Remember, you can send me your "Ask My Instructor" questions for any exercises that are giving you difficulty and I will do my best to point you in the right direction.

"Before we can do the conversion we need to add leading 0's to our base 2 numbers because all of our numbers in base 2 have to have two digits."

Mgf1107 thank you this helped a lot
Melissa Seymour mgf1107 online One thing I liked about the video was that you explained everything and it was very easy to follow along and understand. Converting base 2,4 and 8. The first place value. Thank you so much
You are so welcome!
