A direct proof won't work, so

try contradiction.

Here are the haikus that the Spring 2023 Math 114 students have permitted me to share.

Math equals patterns

patterns not everyone sees

patterns we all need.

Two coprime numbers

Only one common factor

GCD is one

Thank you professor

For giving a glimpse of life

In the real world.

Proving things takes time

Don't assume something is true

Without proving it

Base case is the start,

From 1 to *k*'s inductive,

then we can conclude.

Questions buried deep,

Nonsense starts to have reasons,

Hot dog is sandwich?
