Great question! The +" sign in this formula is actually redundant and doesn't change the outcome of the formula. It's simply a way to indicate to Excel that you want to use a positive number.

In most cases, when you enter a number without a sign in front of it, Excel assumes it's a positive number. However, if you want to be absolutely clear that you're using a positive number, you can include the +" sign.

So, in your formula =+A1, the +" sign is not necessary and you could simply write =A1 and get the same result.

I hope that helps!

1. Enter the formula =A1 instead of =+A1
