You should accept * as an alias for multiplication, as it's the common way to type multiplication on a computer. You should also accept "sqrt" for "squareroot," as it's a fairly common abbreviation.
You're inconsistent about what you include as "all the buttons" on the TI-83. For example, you don't have the STO-> key at all, even though that's the primary function of that key, but you do have it's secondary function, RCL. My suggestion would be to reorganize the TI-83 column so that each actual button has one "space," that recognizes all of it's functions, since this matches your title better.
You should also, for completeness sake, mention that you're ignoring the button functions on the 83 that are accessed by using the ALPHA key, and that you're ignoring the directional arrows. |
