New words: aardvark, aback, abacus, abandon

To be abandon, that I understand,
Though having been taken aback,
While facing an aardvark,
Is way too unusual, for even me to grandstand.

I never have used an abacus,
Not even one time, it seems,
Instead of using a counting board,
I was taught by the old fashion means.
One number added to another number,
'tis the sum of the plus, nothing extreme,
Mathmatical tables in an ole school,
Are memories I recall in daydreams.

New words: baa, babble, baboon, bacalao
