If there is any, the power of is done first, like 10 squared for example. It can be more complex than that, when you bring other elements into calculations. BOMDAS is a way of remembering the order to do things in:
Brackets, power Of, Multiplication, Division, Addition, Subtraction. There are other variations of this: Parantheses, Exponentiation, Division, Multiplication, Addition, Subtraction.
Normally power of, also known as exponentiation is done first, like 102 for example. The only way something else can be done before that is if brackets are used. See the related question below.
Multiplications and divisions from left to right.
Normally the multplication is done first. However you may be suspicious as to why there is a space after the 4.
An operation which when performed multiple times, has no further effect on Its subject after the first time it is performed. - Nacolepsy

The first key you type in Excel to create any kind of formula is the equal sign (=). If you are trying to create an array formula press CTRL+SHIFT+ENTER. Excel surrounds the formula with braces ({ }) and places an instance of the formula in each cell of the selected range.
If the first character of a cell is an equals sign (=), then the cell contains a formula.
Excel formulas begin with an equal sign, for example:=SUM(A1:A7)will give you the total of the numbers in cells A1, A2, A3, A4, A5, A6 and A7.Array formulas start with = but are enclosed in brace bracket{}.You can also use the plus or minus sign to start a formula, but as soon as you press Enter, a plus will be converted into an equals sign and a minus sign will have an equals sign inserted before it, so the formula will still show as starting with an equals sign.+5+7 will become =5+7-10*2 will become =-10*2Lotus 123 was the big spreadsheet application before Excel. It used the @ sign to start its functions. In order to help people moving from using Lotus 123 to Excel, the ability to start functions with the @ sign was included in Excel, and you can still do that. This applies only to functions at the start of a formula, not any formula.
An equal sign because in order for the formula to go through correctly it has to have an (=)

The equals sign. =SUM(B1:B7)
