It's great to see you working through these exercises and putting in the effort to understand binary and hexadecimal number systems. Mistakes are a natural part of the learning process, and it's important to learn from them and keep moving forward.
Keep pushing, and remember that every step, even the missteps, are part of your journey to becoming a proficient developer. You're doing great, and with continued effort and attention to detail, you'll keep improving.

what would be the largest decimal number you can store on 10 bits?

can you please explain to me what do you mean here? (what operation is between "n" and "(n-1)" in this expression?)

a power of two has only 1 in its representation. 0001- 1, 0010- 2, 0011-3 is not power of 2, 0100-4, 0101-5 -is not power of 2. but there is a faster formula we can apply the formula n(n-1) =0, that is a bisewise operation.

well done, and thanks for sharing how you got to the result! (i'll be a nitpicky (and i can see you used "*" to signal multiplication), but i think it's worth 'signaling' if you try to use exponentiation/power of in plain text eg. with ^ - so your expression would look like this: 3 * 16^2 + 8 * 16^1 + 6 * 16^0 = 902 )
regardless, the solution is correct
