How can I reset my Casio FX-115 ES calculator to its default settings


There must be an error in what you report. You pressed MODE then 4: Base-N and now your calculator is in base-N calculation mode (the DEC, Hex, BIN, OCT) numeration keys are active.
To do statistics you must put the calculator in STATS mode.
Press MODE: You have 6 computational modes to choose from
1: COMP, the general computational mode
2:CMPLX, for calculation s with complex numbers,
3: STAT for statistics,
4: Base-N, binary, octal, decimal, and hexadecimal numeration
5: Equation, solving mode, etc..
For statistics, choose 3:STAT

I need to know how to simplify and not factor on my calculator


The Casio FX-115ES does not have a Computer Algebra System (or CAS), so it is incapable of factoring polynomials.
As to simplifications, the only ones that you can get with the FX-115ES are the display of fractions in their irreducible forms.

Sorry.

Convert to/from Decimal/Binary


Press MODE 4 to enter the BASE-N mode. If the display doesn't say Dec, press SHIFT DEC (the x^2 key) to set base 10. Enter the number to convert. Press SHIFT BIN (the log key) to switch to base 2.

Each time you switch the base the current value is redisplayed in that new base.
