The representation of SUM is the capital Greek letter SIGMA (Σ).
The equals sign. =SUM(B1:B7)
You need a formula. That formula can use the Sum function or it could use the plus sign, or several plus signs and even several Sum functions. Primarily it is the Sum function and the plus sign that is used for sums.
An equal sign because in order for the formula to go through correctly it has to have an (=)
SUMIFS was new in Excel 2007.
You type an equals sign into the formula box, type in the sum you want to do using the cell references (coordinates) then click enter
yes
Well, formulas in general don't always start with a sign, but it might be talking about Excel, where they always start with an equal sign (=).
The Sum operator is the plus sign +. You may be referring to the Sum icon, which is the Greek letter Sigma, which looks like a funny capital letter E, or a capital M on its side. It is Σ.
The SUM function.
There are many signs used in Excel. Three of them are the plus sign (+), the minus sign (-) and the multiplication sign (*).
The sum of 7 and 4 is 11, whether in an Excel spreadsheet or anywhere else. In Excel the formula would be =SUM(4,7) or =4+7 or =(B12+B13) if the values 7 and 4 were in cells B12 and B13.
Without it, Excel will treat what you type in as a number, date or text. What you type will then literally appear in the cell. All functions start with letters. If the first thing you type is a letter, then it would be treated as text. The equals sign tells Excel to do the calculation that follows it. If you try typing any formula or function without an equals sign it will just appear in the cell and not do a calculation.
