But why are we being quizzed for grad school math stuff?

x.yz = 10^x-1 + c

(Just to be clear: ^ = exponential notation)

4 - 4/4 + 7 = 4 - 1 + 7 = 10

Using the xyz variables indicates a three dimensional Cartesian coordinate system. And "c" in physics is usually the constant of the speed of light in a vacuum.

It would be easier to read and understand with proper mathematical notation (we are limited on what we can do on KMC unless you take screenshots and post an image with proper maths notation).

Also, I've never seen "x.yz" in math notation like that before unless it represented a decimal. And googling it, it doesn't show up as proper maths notation:

https://math.stackexchange.com/questions/1571294/is-the-period-symbol-ever-used-as-an-operator

Anyway, here is an example of why proper maths notation is needed to understand what it is you're trying to do:

10^x-1 can either be

10^(x-1)

or

(10^x)-1


Other than assuming it is a joke of some sort, I have no other guesses. Since you have what looks like 4 variables in a single equation (or 3 if I am correct about c), it is not possible without further information to solve for the variables represented unless you present a second or even third equation to solve it as a system of equations.

Unless, of course, you want it plotted? In that case, we could solve for z and plot and assume c is speed of light in a vacuum.

Otherwise known as 10. That is incorrect.

4-4 = 0

0 / 4 = 0

0 + 7 = 7

7 imo

Order of operations: you must do the division first.


This is a classic type of question that they would ask 8 year olds in second grade (primary school) to teach them the order of operations.


The reason that this question seems like a trick question is most adults forget about the order of operations that they learned as an 8 year old.

Just to look at it the / would make one that that it is 2 different equations being combined and thus that would make the answer 11, but then I aint no math nerd and made up math BS is just that at times.

This is an FTL formula I had developed years ago for a scifi novel I'd been writing. It's like a warp factor, but instead of the cee-multiple being the warp factor cubed, this formula is by magnitude: basically, it starts at cee (light speed), and each magnitude thereafter is 10x the one before. Examples ...

Magnitude 7 (7.0) =
10^7-1 ---> 10^6 ---> 1,000,000 cee.

Magnitude 4.25 =
10^4-1 + ---> 1000 + ---> 3250 cee.

I believe I delayed the decay of some brain cells that day, when I came up with this.

So I was close. The xyz thing is what was throwing me off. It makes sense, now. The "x.yz" thing is simply number formatting. So you're doing kind of pseudo coding like a dev would do mixed in with a formula. It all makes sense, now, to me.


But it is self-referencing. Unless you're always provided with the warp factor and you just want to figure out actual velocity?


I think it's good stuff. smile

Ooh, close. It's actually 42 according to Douglas Adams.

I buy it.
