Comments on: How to do calculations in Excel

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. Apart from that, 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. Continue reading →

    How I can sum only the number from cells like this FR - 1?

  2. I need to create a formula in a cell that changes based on the value in another cell.

    Is this possible, and if so can someone please provide the formula?

    1. Hello Matthew!
      If I got you right, the formula below will help you with your task

  19. Excel alloys _______ calculation

  20. 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

    1. 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.

  21. 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

  22. hi how to key in this formula in excel =(10000×5266)-(10000×342)/(1.319)×(16841-11368/1.319)-1072.4)^2)*(100+6.0)*(1.458)

  29. 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)

  30. Thanks a lot!!
    That was helpful...

  31. =(B50*C50)+(B51*C51)+(B52*C52)/2.378
    How do I get all three items in brackets to total then divide by 2.378

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

      1. thank you i used this and it worked ty

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

    good programmer keep it up

  33. 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.

    1. 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)).

  34. 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!!

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

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