I have a question related to Numerical methods which is a Comp Sci module so I figured it belongs here. My question is: whenever a question states that an answer must be rounded/chopped to X digits, is it always expected of me to normalize? I'm in a study group and they all state that it is not necessary unless it's specifically asked for.

I also believe I should normalize after every operation like this:
Using 4-digit chopping/truncation:

0.22345 - (23.1864 + 6.02065) / 0.00220239

This becomes:

0.2234 - (23.18 + 6.02) / 0.002202
= 0.2234 - (29.2) / 0.002202
= 0.2234 - 13260.67211625795
= 0.2234 - 13260
= -13259.7766
= -13250

Am I doing this right?
