Changing Numbers To Prescribed Values Under Special Limitations
Posted:
Feb 9, 2013 8:29 AM


x=1825+91/1217 y=7+2/3 z=1827+2/3
Is there any way to turn x into z only using the first two terms, andor a constant, and the operators '+','','*','/'.
I know I can take ((x)(x mod 10)) + y = z, but this uses a modulus.
... Basically the core of the question is can I change any number's last digit and its decimal value to something I decide by only using the number itself and the desired digit and decimal?
... I feel like splitting the numerator and denominator and running independent operations on each might be the way to go.
