Homework question dewdz!

Okay, I can't really read the image, let's see...

Does that work?
The middle part I'm unsure of, that little guy up there looks like an 8. Anyway, I keep crunching the numbers and I always get -23.2125. According to my assignment thing, the answer should be – 22.6740.

I'm using a program called Matlab that's very syntax dependant, any ideas as to what I'm doing wrong? I've also entered it into my TI-89 a couple of times, gotten it to look exactly like that, and still get that same answer. I wonder what the heck that number is up there?

try 3

I already tried that and I came up with -23.2720.
Of course, I didn't bother to do it by hand. I could have messed up the syntax somewhere.

Seems like it would have to be bigger than 8, since you're adding, and I need a "lower" negative number, which means I need to move further right on the number line.

lol we did this kinda stuff in school today. im gunna try doing it with my brain now

it could be an "S" variable, ya know?

 

[D-Lew]

In matlab, each variable has to be defined and I have not entered a value for S in this one.

Edit:
Problem solved!

It turns out that -3 and whatever/whatever is a *gasp* MIXED NUMBER!
How about that, folks?

I was multiplying for some reason, getting -69/13 for that number. For some reason it confused me.
