The math operators in Excel have an order of operation, just like in regular math. The order of operation is the order in which they’re processed when multiple operators appear in the same formula. Here are the rules that determine the order:

1. Any operations that are in parentheses, from left to right
2. Exponentiation (^)
3. Multiplication (*) and division (/)
4. Addition (+) and subtraction (-)

Parentheses override everything and go first. So, if you need to execute an operation out of the normal order, you place it in parentheses.

For example, suppose you have this formula:

=5+16/4^2

The order of operation looks like this:

1. The exponentiation (4^2 equals 16)
2. The division (16/16 equals 1)
3. The addition (5+1 equals 6)

The result of the formula is 6.

If you wanted the addition to occur first, you could put parentheses around the addition portion of the equation, like this:

=(5+16)/4^2

This time, the order of operation looks like this:

1. The part in parentheses (5+16 equals 21)
2. The exponentiation (4^2 equals 16)
3. The division (21/16 equals 1.3125)

The result of this formula is 1.3125.

If you wanted to perform the exponentiation last, you could add another set of parentheses, like this:

=((5+16)/4)^2

Now the order is this:

1. The inner parentheses (5+16 equals 21)
2. The outer parentheses (21/4 equals 5.25)
3. The exponentiation (5.25^2 equals 27.5625)

The result of this formula is 27.5625.

If you left off the inner set of parentheses and wrote it like this:

=(5+16/4)^2

The order would be as follows:

1. The division, because it’s the highest-ranking operation inside the parentheses (16/4 equals 4)
2. The rest of the parenthetical operations (5+4 equals 9)
3. The exponent (9^2 equals 81)

The result of this formula is 81.
