I am a math geek. I am known at work as the person who can get anyone to understand how to do algebra. I can create multi variable equations to determining what numbers a company is using in figuring their costs during a contract negotiations. I know math – and I’m not afraid to use it.
I am also not above math tricks. For example, the 9 multiplication tables and your fingers trick is a trick I showed my husband who now teaches it in school (after of course he has made them learn it the right way). Imagine then, my joy when I discovered this trick today:

Never will I wonder what the conversation rate between mile and kilometers is again. Now if someone will point me to a trick like this one that will work when converting from Fahrenheit to Celsius.
