Multiplication is
vexation,
Division is as
bad;
Rule of Three doth
puzzle me,
And
Practice drives me
mad.
From The Real Mother Goose
Variations:
The third line can be:
The rule of three it vexes me.
The rule of three perplexes me.
The last line can be:
And fractions drive me mad.
There can be no doubt: Maths are bad. Right?
