a = a * 2
Now, getting past the substitute of * for X as an indicator of a multiplication operation, most CS-types will interpret this as a command to double the value of a while a math-type would instead view this as a statement of fact (within the scope of the problem) and infer from this (probably without even thinking about it) that a is zero because no other value satisfies the formula.
Now I wouldn't identify as a "math-type", but I'm pretty sure we could infer a = 1 as an alternative to a = 0
