*The tutorial shows how to do arithmetic calculations in Excel and change the order of operations in your formulas.*

When it comes to calculations, there is almost noting that Microsoft Excel cannot do, from totaling a column of numbers to solving complex linear programming problems. For this, Excel provides a few hundred predefined formulas, called Excel functions. In addition, you can use Excel as a calculator to do math - add, divide, multiply, and subtract numbers as well as raise to power and find roots.

Making calculations in Excel is easy. Here's how:

- Type the equal symbol (=) in a cell. This tells Excel that you are entering a formula, not just numbers.
- Type the equation you want to calculate. For example, to add up 5 and 7, you type =5+7
- Press the Enter key to complete your calculation. Done!

Instead of entering numbers directly in your calculation formula, you can put them in separate cells, and then reference those cells in your formula, e.g. =A1+A2+A3

The following table shows how to perform basic arithmetic calculations in Excel.

Operation |
Operator |
Example |
Description |

Addition | + (plus sign) | =A1+A2 | Adds up the numbers in cells A1 and A2. |

Subtraction | - (minus sign) | =A1-A2 | Subtracts the number in A2 from the number in A1. |

Multiplication | * (asterisk) | =A1*A2 | Multiplies the numbers in A1 and A2. |

Division | / (forward slash) | =A1/A2 | Divides the number in A1 by the number in A2. |

Percent | % (percent) | =A1*10% | Finds 10% of the number in A1. |

Raising to power (Exponentiation) | ^ (caret) | =A2^3 | Raises the number in A2 to the power of 3. |

Square root | SQRT function | =SQRT(A1) | Finds the square root of the number in A1. |

Nth root | ^(1/n) (Where n is the root to find) |
=A1^(1/3) | Finds the cube root of the number in A1. |

The results of the above Excel calculation formulas may look something similar to this:

Apart from that, you can combine values from two or more cells in a single cell by using the concatenation operator (&) like this:

`=A2&" "&B2&" "&C2`

A space character (" ") is concatenated in between cells to separate the words:

You can also compare cells by using logical operators such as "greater than" (>), "less than" (<), "greater than or equal to" (>=), and "less than or equal to" (<=). The result of comparison are logical values of TRUE and FALSE:

When you do two or more calculations in a single formula, Microsoft Excel calculates the formula from left to right, according to the order of operations shown in this table:

Precedence |
Operation |

1 | Negation, i.e. reversing the number sign, as in -5, or -A1 |

2 | Percent (%) |

3 | Exponentiation, i.e. raising to power (^) |

4 | Multiplication (*) and division (/), whichever comes first |

5 | Addition (+) and subtraction (-), whichever comes first |

6 | Concatenation (&) |

7 | Comparison (>, <, >=, <=, =) |

Since the order of calculations affects the final result, you need to know how to change it.

Like you do in math, you can change the order of Excel calculations by enclosing the part to be calculated first in parentheses.

For example, the calculation `=2*4+7`

tells Excel to multiply 2 by 4, and then add 7 to the product. The result of this calculation is 15. By enclosing the addition operation in parentheses `=2*(4+7)`

, you instruct Excel to add up 4 and 7 first, and then multiply the sum by 2. And the result of this calculation is 22.

Another example is finding a root in Excel. To get the square root of, say, 16, you can use either this formula:

`=SQRT(16)`

or an exponent of 1/2:

`=16^(1/2)`

Technically, the above equation tells Excel to raise 16 to the power of 1/2. But why do we enclose 1/2 in parentheses? Because if we don't, Excel will raise 16 to the power of 1 first (an exponent operation is performed before division), and then divide the result by 2. Since any number raised to the power of 1 is the number itself, we would end up dividing 16 by 2. In contrast, by enclosing 1/2 in parentheses you tell Excel to divide 1 by 2 first, and then raise 16 to the power of 0.5.

As you can see in the screenshot below, the same calculation with and without parentheses produces different results:

This is how you make calculations in Excel. I thank you for reading and hope to see you on our blog next week!

Could you show us how to build a financial model in Excel?

Hi, I have a 2 part question.

1st, upon looking at my formula to try to reverse engineer it, I noticed the math seems a bit weird. I have this formula to calculate the amounts of 2 components based on the ratio and the total weight (tw=total weight, ra=ratio a, rb=ratio b, aw=weight of part a, bw=weight of part b. I'll use these instead of the cell #'s here). My formula looks like this bw=tw*(rb/(ra+rb)) and the formula for the other part is ra=tw*(ra/(ra+rb)).

the issue is that when I do out the math in steps, based on order of operations, I get a decimal, but the formula gives me a whole #. Why don't I get the same result?

Part 2; how can I create 2 formulas that will solve this backwards, as in, plug in the weight of a or b and get what my total weight and the weight of the other part as a result?

Thank you so much! I've been cracking my brain open over this for days and searching all over the web for an answer that I don't know an easy question to!!

sorry, messed up the 2nd formula, that should be aw=tw*(ra/(ra+rb))

One last point, sorry to go on:

to illustrate, I'll plug in 66 as the tw, 100 as ra and 10 as rb. in the formula I get 60 and 6 for a and b, which seems like it did not respect the parenthesis, as 66*(100/(100+10))= 66*(100/110)= 66*0.9090909091= 60.0000000006, while 66*100/(100+10)=6600/110=60 which is what the formula gives me.

Hi Rae,

1. Your formula is correct, you do not get the same result because of

rounding off. Check the result again with this formula (it will round to 10 decimal places):

=TEXT(66 * ROUND((100 / (100 + 10)),10),"0.0000000000")

2. Try these formulas:

tw= aw/(ra/(ra+rb))

or

= TEXT(60 / ROUND((100 / (100 + 10)),10),"0.0000000000")

tw=bw/(rb/(ra+rb))

or

= TEXT(6 / ROUND((10 / (100 + 10)),10),"0.0000000000")

And your last point, try the following:

bw=(aw/(ra/(ra+rb)))*(rb/(ra+rb))

aw=(bw/(rb/(ra+rb)))*(ra/(ra+rb)).

You are so good, I've learn a lot from you expecially the capitalization and the calculations.

good programmer keep it up

=(B50*C50)+(B51*C51)+(B52*C52)/2.378

How do I get all three items in brackets to total then divide by 2.378

Formula is =((B50*C50)+(B51*C51)+(B52*C52))/2.378

Thanks a lot!!

That was helpful...

Hey! how do i divide a number into 10000, 5000, 1000 and 250? (For ex. I want to divide 77350 into 7(10000) 1(5000) 2(1000) 2(250) so it would also round up to 77500 (the numbers should end either by 000, 250, 500 or 750)

We'll do our best to help you.

Can I configure cells to automatically calculate pre-determined costs prior to entering the primary value? i.e. if I have a fixed shipping cost but the price of the product varies.

Can you advise how to set up excel to execute this formula.

13.6 x [(SL + SS) – W.T.] x W.T.

I'm trying to set up a spreadsheet for a user to input SL, SS and W.T. to calculate the weight of an item.

Formula: Qty-QtySold-Qtyreturned

If I start with 4 -1-1 it will equal 2 This is Correct

If I start with 4 and leave blank the sold or returned fields the result shows BLANK.

I am so frustrated and cannot figure out what is wrong>>>> Please advise Thank you.

I am not the most skilled at excel , but am enjoying the discovery as i go.

In creating a calculating option for a tool i am working on, I am wanting the number 1 to calculate to total a maximum of 5 as 1 is selected from a drop down option.

Using conditional formatting and data validation i cannot get the the numbers to add when i want to determine a difference with the same number.

For example i have selected number 1 in the drop down list for selection along with other choices. The selection I want is listed below (as laid out in data validation.)

1, 1L, 1E,

I want 1 L and 1 E a certain color like green (using Conditional formatting) to pop up automatically as 1 L or 1 E is selected.

I want the number 1 alone to have no color

I want to have all the number 1'S to calculate as they are selected

1 L and 1 E dont calculate (1 and anything i put dont calculate, )

is there a way?? Can you help?

I hope this makes sense

Thank you for your time

hi good day

while typing my stuff in excel and trying the calculate when I put a =B1+B2 the part with the B2 turns to read and the end product just says value can u all tell me where I went wrong

Hello Kerleisha!

Probably, the error occurs because you have a number in one of the cells and the other cell contains a symbol, e.g. a space.

If it is not the case, please describe the problem in more detail so I will be able to help you better.
