PLEASE HELP ON QUESTION ASAP !

hi ! I really need help understanding paragraph and I've also added a question about paragraph by me down below . Would like explanation in simple words.

If answers correct I'll rate you five stars a thanks and maybe even brainliest


Paragraph I needed help understanding:

If two or more cells are connected together side by side, the voltage across them is sum of the voltage of each cell. This is because both cells are pushing same way.



My Question about paragraph:

If the sum lets say was 4.5v would every individual cell be worth 4.5 as it says in question ' voltage across them is the sum of voltage of each cell ' or are they each a different value? And how would we be able to find value?.
