Ok so for context, am having a surprise math test tomorrow and I've not studied at all. This morning, i decided to try to study. I have a question on binary number system. (1101 in base 2)^ - (111 in base 2)^2. Thanks

In binary, the values of the first four positions, from right to left, are 1, 2, 4, 8.

So 1101 (base 2) means you have, from right to left, one 1, no 2's, one 4, and one 8. Add them up and you have the value of 1101 (base 2).

Do the same for the other number, and then (assuming the ^ indicates exponent) apply the rule for raising to a negative exponent, which I presume you can find if you don't remember it.
