or expression?
Note the absence of an equal sign.
However, when you populate the "formula" (if that's what it is) it decidedly
becomes an equality viz. equation, e.g., 2^3 * 3^2  5 = 67
(all integers in the set of natural numbers not divisible by 2, 3 and 5 can be
generated with this "formula") (ref: www.primesdemystified.com )
