Evaluate a mathematical expression and propagate measurement uncertainty. Use ± for measurements, for example 2*x with variables {"x":"3±0.1"}. Variable names are single ASCII letters; lowercase e is reserved for Euler’s number. Pass variables: {} when no variables are needed. Results include raw and rounded values and human-readable and LaTeX expressions. Measurements are treated as independent; repeated uses of the same variable share its uncertainty.
