Conditions: does moving fields break calculations or conditions?

If I switch the positions of these two sections: 

Insights Ads: Select Your Frequency & Size 

with

Insights Ads: Select Which Issues to Advertise in

will it affect the calculations?

No moving your fields shouldn't break your conditions. They are quite robust. They will even continue to work if you rename them. The only thing that will break your conditions is if you delete a field.

If for any reason your conditions did break you can easily revert your form to a previous saved state.

Please see this guide:

Thanks, but I was asking about the calculations being affected, not the conditions.

Sorry for the confusion. The same applies to calculations.
