    I want to ask you a question about that.
    For example when I multiply 20 with cos25, should I round the result to 20? Because 20 has the least significant figures.
    20*cos25=20?

    But you can do one thing since the number is not decimal, you can still keep it as 4300.
    Or maybe write it as 43*10^2 to not get backlashed from the examiners for not writing something or writing the same thing.
