The scenario is I am going to show how to process many uncertainty terms in the calculation, but the title of the slide should be "uncertainties in calculation" or "uncertainties in the calculation?" I feel it is more appropriate to use the latter one, but what's the subtle difference between these two?enter image description here

It's about: When we need to do a calculation on the quantities that have uncertainties, how do we do it? For the case including addition or subtraction... Please refer to part of the slide I uploaded.

    Is the slide talking about one specific calculation ("uncertainties in the calculation"), or about the principles of calculating things more generally ("uncertainties in calculation")? – nnnnnn Aug 15 '19 at 6:40
  • It depends what is meant by ‘a equals b plus-or-minus c’. What does this mean for any value of b and c such neither of them is zero? If both b and c have non-zero values, then surely ‘a = b plus-or-minus c’ is not a well-formed formula? – Tuffy Aug 15 '19 at 8:42

"uncertainties in calculation" or "uncertainties in the calculation?"

I would guess that you wish to show, that

"uncertainties should be considered when making (Doing) a calculation"

But what you have written is

In the calculation by which you mean the uncertainties form part of the calculation for example x=y*z-(uncertainties) where uncertainties are Blah Blah Blah!

in calculation, which is the act of calculating something, so this means you are not confident that the calculation has been done in a correct manner.

How about calling the slide Calculations; Consideration of Uncertainties This should cover all bases, no matter what your meaning is.

calculation: noun; the process of using information you already have and adding, taking away, multiplying, or dividing numbers to judge the number or amount of something: Cambridge English Dictionary
