mistakes in calculation

the program made a mistake in the final answer, giving an interim calculation of the following:

b(a-3b)+(a+b)(a-b)-ab

the print screen is attached.

ab -ab =0 so it should not be in the final answer

Please ensure that you input the term ab as a*b or a b (with a blank space between a and b)

If you don’t, GeoGebra won’t recognize that monomial term correctly.
