If one did not know the standard precedence of arithmetic operations,
one would certainly want extra parentheses. For example

2 m^2 (s - 1)

might be misinterpreted as

(2 m) ^ (2 (s - 1)).

Even worse for

m^2 (s - 1)^2,

which for one order of operations has the added benefit of causing
confusion due to the non-associativity of exponentiation.
