How to make magical words.

Word magic, well best start with nothing. That is really boring so im going to make:
 There is only addition and subtraction in word magic, and combination can be taken away if one part is negative.

I

I + U = UI : UserInterface - 5 Syllables - 13 letters

I + S = Is

i + s + u = us + ui

i + s + u - ui = us

s = us

= us - s

= u

since one is lonely it creates a mirror of itself

n = u

no = uo : Urate oxidase - 6 Syllables - 12 letters

Urate oxidase + 1 Syllables + 1 letter = UserInterface

1 Syllable + 1 letter = UserInterface - Urate Oxidase

1 Syllable + 1 letter = notracfetxd

1 Syllable = notracfetxd - 1 letter (removed t(time) from equation)

 1 Syllable = notracfexd

nofexd : 2 Syllables - 6 letters
notrac : 2 Syllables - 6 letters
tracfexd : 2 Syllables  - 8 letter
notracfexd : 3 Syllables - 10 letters

 1 Syllable - 3Syllable= notracfexd - 3 Syllable

 -2 Syllable = nothing(or a word that means nothing) tracfexd
