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.
Alt Codes for Basic Operators
Alt 0215 × Multiplication Sign
Alt 0247 ÷ Obelus / Division Sign
Alt 37 % Percentage Sign
Alt 0137 ‰ Per mille (per thousand)
Alt 241 ± Plus or Minus
Alt 0188 ¼ Quarter
Alt 0189 ½ Half
Alt 0190 ¾ Three quarters
Alt 240 ≡ Exactly Identical
Alt 247 ≈ Approximately equal
Alt 242 ≥ Greater than or equal
Alt 243 ≤ Less than or equal
Alt 251 √ Square Root
Alt 252 ⁿ Power n
