Do you know the hierchy (BODMAS or PEMDAS or similar acronym)? If you do, carefully follow that.

Please show your work, step by step, so we can see where you went wrong.

You can just type these into many calculators, just as they are written, and get the answers; but even then you need to be careful that you type exactly what you mean.

Hi dskoli. We evaluate expressions by following the Order of Operations.

Were you instructed to round your answers?
