- Squaring two digit numbers in your head (blog.jgc.org)
All my life I’ve done mental arithmetic the ‘wrong way’: I’ve calculated from left-to-right, instead of right-to-left. So when I do something like 24 + 35 I’ll see the 50 first and then the 9. This even applies when there’s a carry and I’ll do something like 36 + 56 as 80 + 12. I do the same thing for multiplication as well.

The Columbia Center, formerly named the Bank of America Tower and Columbia Seafirst Center, is a skyscraper in downtown Seattle, Washington, United States. The 76-story structure is the tallest building in Seattle and the state of Washington, reaching a height of 933 ft (284 m). At the time of its completion, the Columbia Center was the tallest structure on the West Coast; as of 2017, it is the fourth-tallest, behind buildings in Los Angeles and San Francisco.
