Excel公式栏中等号后加号的含义咨询（含公式示例）

Hey there! Let's clear up that confusing plus sign you're noticing right after the = in your Excel performance metric formulas. Short answer: it's completely redundant—Excel ignores it entirely, and it doesn't change how your formula calculates.

Why Does It Exist? #

That + is a holdover from older spreadsheet software (specifically Lotus 1-2-3, which was dominant before Excel). In Lotus, formulas started with a + instead of =, like +A1*B2. When Excel launched, it added compatibility for this syntax—so if someone types =+..., Excel just treats it the same as a standard = formula.

Over time, it's also become a habit for some users: either out of muscle memory from Lotus, or as a way to "visually flag" that the cell contains a calculation (even though the = already does that).

Breaking Down Your Examples #

Let's walk through your specific formulas to confirm this:

• =+O6*(1+B7): This is identical to =O6*(1+B7). The leading + does nothing—Excel will calculate the product of O6 and (1+B7) exactly the same way without it.
• =+EY203*(1+'Product Performance Monthly'!J261): Same deal! Remove the + and you get =EY203*(1+'Product Performance Monthly'!J261), which works perfectly and returns the same result.
• {=+PRODUCT(1+FA$208:FA209)-1}: Even in this array formula, the + is unnecessary. The critical part here is the curly braces (which are added automatically when you press Ctrl+Shift+Enter, not typed manually), not the leading plus. Removing it gives {=PRODUCT(1+FA$208:FA209)-1}, which calculates the compound growth exactly as intended.

Should You Remove It? #

Absolutely! Those plus signs don't serve any functional purpose. Deleting them will clean up your formulas without affecting their output. If you're working with a lot of these, you can use Excel's Find & Replace tool:

1. Press Ctrl+H to open Find & Replace
2. In the "Find what" field, type =+ (make sure to include the equals sign and plus)
3. In the "Replace with" field, type =
4. Click "Replace All" to strip out all those redundant pluses in one go
