The stars that you show in your
equation means multiplication,
but they are not normally shown
in equations; because it is under
stood to mean multiply. The equation
is normally written like this:
4(3XY) = 81XY.
I hope I have answered your question.

This is not an equation; 12XY
DOES NOT EQUAL 81XY.

So would you consider this equation correct if so why and if not why not?

This is correct: 12XY < 81XY, In other
words, 12 apples are less than 81 apples. So this is an inequality.
