Hi there, Agnieszka Uchacz! To do the calculation, start at the far right of this number. Note that I will be using ^ to represent "to the power of". You will end up with the following expression:

(1 x 2^0) + (1 x 2^1) + (1 x 2^2)

This is equivalent to:

1 + 2 + 4

So the final value will be 7.

Hope this helps! :sparkles:

Hey there!

This handbook may help with Bitwise & Binary Conversion (pages 77-80)n: https://github.com/ChairBearLearning/software-theory/blob/master/Software%20Languages%20Theory.pdf

You'd find the binary conversion table helpful - it outputs the value 7 for you.
