Excerpt from Shop Mathematics
Plus and minus are also used to indicate positive and negative quantities.
X, times, or multiplied by, is the Sign of multiplication. A dot is sometimes used for x where the quantities are expressed by letters, but is usually omitted in algebraic formulas; thus a X b, or a b is ordinarily written ab.
