If you add an equals sign at the end of a cell, RoboSheets automatically evaluates it as a mathematical expression.
The basic math operators are + - *, and /. For more advanced expressions, Robosheets supports writing arbitrary Javasript
. For example, you might write `Math.sqrt(5)=` to get the square root of five.
When you copy a math cell, Robosheets only copies the value it computed.
