First let us know what is a homonym or homophone. A word that is pronounced the same way as another word but has different meaning is called a homonym.

Examples: Hair and hare; right and write; piece and peace etc.

√(-1) is an imaginary number represented by 'i'.

2³ = 8 (eight). Its homonym is 'ate'.

Σ stands for sum (or total) whose homonym is 'some'.

Finally, π is a homonym of 'pie'.

The symbols when decoded mean "I ate sum pie"..... and it is very delicious!

It can also be "I ate total pie"..... and it is very delicious!
