They literally mean the same thing - just one is used in some countries and the other is used in other countries.
Yes they both are multiply, but...
Calculate 8 ÷ 2a where a = 4. Then,
Calculate 8 ÷ 2 × a where a = 4.
See how in the first form a is implied to be part of the fraction where in the second it isn't?
A dot • could be between 2 and a and it would still follow the first example. In vector multiplication, dot and cross products produce different results.
