Discussion on: Daily Challenge #160 - Expression Matters

proc expressionsMatter(a, b, c: Natural): Natural =
  ## Accepts three numbers in the Natural range [0..high(int)], then
  ## returns the maximum value after inserting parentheses, addition
  ## operators, and multiplication operators in any order.
  result = max(result, a + b + c)
  result = max(result, a * b * c)
  result = max(result, a + b * c)
  result = max(result, (a + b) * c)
  result = max(result, a * b + c)
  result = max(result, a * (b + c))
