One technical question of Spreadsheet

Alsa

For Spreadsheet, i am confused. Why is there usually with symbol"+" in front of the formulas?
Is it compulsory? If not, does it mean wrong answer?
I do not understand, can somebody explain it? I put one example below and circle the technical part.
Thank you very much.

You shouldn't lose marks for not including the +. It's just using a formal notation for the default setting.

If I write the number 10, we naturally assume that it's +10 and not -10 as that's the default we use the computer is just displaying it on the equations.

Oh, it will spare, and glad to hear it.
For the + symbol. Do you mean that it is setted default in that excel for output the answer.
If i do not set it, then use the excel in the computer, so there is not + symbol output.

You do not need to worry about the +

The number 10 on it's own is the same as writing +10 I'm not sure what setting would cause it to do that but that's all it is and you should not lose marks for having it appear in the exam.

Ok, see.
Thank you for your answer.
