Comedian Demetri Martin wrote a 224-word poem that is a palindrome. That is, if you remove all spaces and punctuation, the string of letters reads the same forward as it does backward.

When I heard about this, I started thinking about palindrome equations—if you remove all the operators (e.g., +, - ×, ÷, etc.), the number string reads the same forward as it does backward. Turns out, it’s easy to make palindrome equations. For example:

0 × 12,345,543,211,234,554,321 = 1,234,554,321 – 1,234,554,321 + 0

So, creating palindrome equations is not particularly tough. Nonetheless, I decided to create some that weren’t trivial—they don’t involve multiplying or dividing by 1 or adding or subtracting 0. Here are some basic multiplication equations (the numeric palindrome is shown in parentheses):

- 0 + 0 = 0 × 0
- 1 + 2 – 3 = 3 – 2 – 1
- 1
^{22}= 2 ÷ 2 ÷ 1

0 × 12,345,543,211,234,554,321 = 1,234,554,321 – 1,234,554,321 + 0
