Question about Casio MS-80TE Calculator

Question I am a ten-year old.  My math homework asks why is there a zero missing in the display when you divide $5.00 by 2?  Can you please help me because my mom doesn't have the manual anymore so I can't look it up.  Thank you for helping me.

:D there's nothing wrong with the calculator. it just does that because it expects you to know the zero is there.

If you divide 5 dollars by 2, you should have $2.50 or 2.50 as shown on the calculator. I could not find this manual on Casio's website. Perhaps you could email them and see if they have a PDF copy they could send you.

How do I figure this average?

Your 116 is 580 divided by 5 grades. The 5th grade was a zero which pulled the average down. You only get a higher score if you don't count the final and thus divide 580 by 4. Your score appears to not depend upon the number of questions asked but the number of tests given and the number of questions answered correctly. That is a bit odd. Typically, a score is the number of right out of the number of questions asked. Then you average those percentages across the number of tests. I suspect this second method is what you are looking for! Convert all to a percentage but the final exam which is a zero. Add the percentages and divide by 5. The zero score is what is dragging your score down.

Instant economy displays 99 when idling.

did you scan the PCM for DTC errors? first? if not why not?
this toy only works when all else works, so....
if not ,ask the dealer.
when going zero miles per hour there is no MPG.
do the math, ?
distant traveled divided by fuel consumed is.
0 div / fuel rate = 0 see? 0 /1000 is 0,

I made my own tool and it shows 200 for that and 200 for divide by zero. (when you drive and cut throttle the injectors cut fuel so fuel is zero, causing divide zero errors. ( 10 miles / 0 is ( div by zero error)
so i trap both those errors, in my software, with 200 flag , the 200 means, (can not compute MPG) see? or I could use 999.

since i didn't design the jeep PCM , i cant tell you there traps.
its just toy. but is ok cruising, use that when moving,
MPG stopped is 0.

have you tried cut fuel mode yet?
drive fast , cut throttle, hot engine, in gear, and fuel is 0 flow.
try that, and watch what it does, what you see is what you get.
my other car , with full obd2 tools, shows 190 mpg.
and is real.
see that here. buddies, top scan tool live data. and plot.

some cars use injector pulse width (flow) to compute MPG
other use MAF air flow. and reverse compute injector rates, (tricky ask)
does this help?
my 2002 jeep has my home made MPG gauge from scratch.

- 7/8 is less than - 5/8 because it is further from zero on the minus axis.

Both numbers are multiple of 100 (the two zeros at the end). Divide both numbers by 100 (remove two zeros from each). You are left with 20/6. Now divide each number by 2 to get 10/3. Use the technique you learned to calculate the result.

I have a very strange math teacher that collects old math books.One day i asked him how many old math books he has.Being a math teacher, he responded, "if i divide the books into two unequal whole...

Your teacher has 64 old math books.
Define the variables:
n = the total number of books x + y = the number of books divided into two groups (x being one set of books and y the other)
Equation set-up from the problem:
64(x - y) = x^2 - y^2
Work it out:
64(x - y) = (x + y)(x - y)
64(x - y) = (x + y)(x - y) (x - y) (x - y)
64 = (x + y)
Therefore, 64 = n
