Yes, the man who revolutionised personal computing couldn't leave the math out even at his wedding. Sharing the clip on Facebook, Melinda wrote, "We told you it was time to cut the cake.

In the video, Melinda couldn't hold back from laughing at Bill Gates' quick fix. Remembering how funny the whole episode was given that there were also sheets of cardboard in the middle of the layered cake, she added, "This is the moment I realized what was happening—and also the moment you realized that cake had a cardboard middle and I had forgotten to mention it. I laughed so hard I couldn’t speak."
