Inequality, geometry, and other math symbols from a windows keyboard

When I am doing math with students I often find using the text tool the most efficient way of quickly typing a math problem. The equation editor is awesome but can be overkill, think: a simple inequality.
 
x + 37 ≥ 45
 
I printed this list so I can make symbols like ≥ and ≈ easily. I hope this link helps others.
 
To use: click the text tool and add regular keyboard symbols. When you want to add a mathematical symbol (make sure num lock is on) hold the Alt key on the left side of your keyboard and while still holding Alt use the numbers on the NUMERICAL KEYBOARD (the numbers across the top of your keyboard won't work) that correspond to the symbol you want to insert. Note some begin with 0 and some do not.
Alt 0247 ÷ and Alt 247 ≈ give totally different results.
Enjoy!
