1. Consider the two words PLUM and SINUS. A simple change will produce an interesting result. Can you determine what it is?

2. Consider the following unrelated words:

ONSET

NEWS

WRONG

HORNET

The same change to each of the words will result in four new, but related, words.

HINTS:

1. It has to do with exchanging letters between the two words.

2. It has to do with anagrams.

Answers:

1. Exchanging the M from PLUM with the S from SINUS gives PLUS and MINUS.

2. The anagrams of the four words rhyme.

ONSET - STONE

NEWS - SEWN

WRONG - GROWN

HORNET - THRONE
