Rythm,
Tell you what? Actually you are poor in Mathematics not English! See I will find you a solution for you:

Let x be the misspelled name of Rythm

x=Rythm
a=int(x/10000)=R

x=x%10000=ythm
b=int(x/1000)=y

x=x%1000=thm
c=int(x/100)=t

x=x%100=hm
d=int(x/10)=h

x=x%10=m
e=x=m

Mutlitplying b by h
b*h=hy

New name of Rythm after correction:
xnew=a*10000+b*1000+c*100+d*10+e=Rhythm

You got it?

Good! Now you sound like a smart UTAian :-)

Welcome to Sajha, Rhythm!
