We define addition in a different way than usual; an addition statement is true only if the letters in the addends is a rearrangement of the letters in the sum. For example,
10 + 6 = 16?
TEN + SIX = TENSIX = SIXTEN, but to be 16 it would need another E.
Find a "true" addition
a + b = c + d.

sixteen + seven = seventeen + six

fourteen + six = sixteen + four

fourteen + seven = seventeen + four

fourteen + nine = nineteen + four

sixteen + nine = nineteen + six

seventeen + nine = nineteen + seven
