Answer: 35.078 to 3 significant figures

Step-by-step explanation:

Solving;

34.56 + 42.235 * 0.0123 - 0.001

We solve the multiplication first according to the BODMAS rule.

So,

42.235 * 0.0123 = 0.51949

Doing the addition,

34.56 + 0.51949 - 0.001

This gives;

35.079 - 0.001

And finally the subtraction gives;

= 35.078
