About Mobius Syntax Fixer
Mobius Syntax Fixer (MSF) removes the annoying quirks of Maple syntax, which is used in Mobius. For example:
When you type "5x" MSF will translate that too "5 * x". Without MSF, the answer that is mathematically correct would be marked as false. Here are other examples of syntax that MSF:
5xy -> 5 * x * y
5xy(2x + 3) -> 5 * x * y * (2 * x + 3)
|3y - 92| -> abs(3 * y - 92)
sqrt(5|2x + 3|) -> sqrt(5 * abs(2 * x + 3))
e^x -> exp(x)
e^(12y - 5) -> exp(12y - 5)
The conversion happens automatically whenever you press:
"How did I do?"
