March 14 is International Day of Mathematics and the theme for this year is "mathematics unites". To celebrate, the International Mathematical Union and various supporting organisations have launched a photo challenge, inviting you to submit a photo of yourself with a mathematical object. Since maths is everywhere, this object could be almost anything — something you drew, made, formed with people's bodies, or spotted in the world around you.

You can submit your photos on the International Day of Mathematics website until March 1, 2022. The best ones will be shared in a gallery.

Everyone can participate. Share the challenge in your school or university. Team up!
