Use math to measure syllables and stresses in meter and structure. Some types of poetry have a very rigid structure. For example, a sonnet must contain 14 lines written in iambic pentameter. A haiku has three lines and a total of 17 syllables. Counting out the rhythm is one way to use math in your writing.
Translate symbols and algebraic expressions into written word problems. This will help familiarize you with representing math in terms of letters instead of numbers. This also gives the expressions a more rhythmic quality. For example, "1 + 1 = 2" becomes "Two is the sum of one and one."
Assign numeric values to elements of a poem. For example, a line that reads "Being alone is better than being with you" might instead become, "One is greater than two with you." If not numeric, you can also use algebraic variables to represent ideas, such as 'x' or 'y.'
Integrate mathematical terms into the poem. Use words such as greater than, sum, product, quotient, function, equals or minus to incorporate the language of math into your written expression. These words are especially powerful when written in a rhythmic and countable meter.
Reference proofs from symbolic logic in your poetry. For example, "If 'p' then 'q.' Proofs deal with theories instead of hard numbers. They are used to express ideas, much like poetry.
