A Todos

Take Christmas, mix in my love of math and add a little interaction with the Spanish language and this is what you get:

A Todos
A todos, Feliz Navidad
Merry Christmas, everyone
Five times five is 25
And one times one is one

A todos, Feliz Navidad
Merry Christmas all of you
Six plus six will get you 12
And one plus one makes 2

Joy to the World the Lord is come
Let earth receive her king
Let every heart prepare Him room
And heaven and nature sing

A todos, Feliz Navidad
And Merry Christmas too
Seven squared is 49
And half of four is two.
