$\large \color{#3D99F6}1 - 2 + 3 - 4 + 5 + 6 - 7 + 8 - 9 = 1$

$\Rightarrow \!\,$ So the answer is Yes

You should change the topic to ''Logic''.

@Syed Hamza Khalid – Here's a good way to give a link

You need to use

$\text{[Text](Link)}$

For example: The text is ''Brilliant'' And the link is https://brilliant.org/

$\text{[Brilliant](https://brilliant.org/)}$ appear as Brilliant

The answer can't be 'I don't know'. If the answer 'Impossible !' was correct, the answer 'No' would also be, and vice versa, so neither of those answers can be correct. So by trial and error, you find the answer must be Yes.

@A W, i read your profile it was so funny ps nice job!!!
