Re: Need help with a math problem

What's the question here?

Isn't the Boolean product of x, y, and z, where each variable is 1, always going to be 1???

How is this a question? Maybe I'm having a brain fart, but I don't understand what they're asking.

I don't understand it either. Can you take a picture of the question? Some data may be getting lost when it gets typed up.

Re: Need help with a math problem

Ditto RHD's reply. If they're all true then any operations will always result as true.

Re: Need help with a math problem

Oh, I get it. It's (e)

The only one that has each variable as-is, no line above it indicating a complement.

Stupid question. Barely a question.

Where did this come up?

Re: Need help with a math problem

here is another one of the work sheet questions

Consider an algorithm that uses only assignment statements that replaces the quintuple (v, w, x, y, z) with (w, x, y, z, v). What is the minimum number of assignment statements needed?
