Assuming that is the only change and the equation is strictly addition, then the sum remains unchanged.

The bottom line (literally) is you are adding zero to the total.

My turn, what happens when I answer your question?

How do i calculate 1.734 = (1+r)5 and get 1.1164. I keep getting an answer of 6.58

you have to know the value of r and then you follow the maths laws of multiplication.division , addition and subtraction in that order
so 1.734 = the sum of 1+r, multiplied by 5

How do you subtract on Microsoft excel

  1. Select a cell
  2. in the Fx section type =SUM(

  5. modify the Fx to read =SUM(C3-
  6. Click another cell
  7. Fx should read (for instance) =SUM(C3-D3
  8. Modify the Fx to read =SUM(C3-D3) by adding a closing bracket
  9. Put a number in C3
  10. Put a number in D3
  11. B3 will display the result of the subtraction

Find the smallest two consecutive even integers such that three times the smaller is at least 19 more than the sum of the two integers

Let x be the smallest number.
Let x + 2 be the other number (consecutive even integer)

Now to translate the rest;)
three times the smaller 3(x)
19 more -19
sum of the two integers - (x) +( x+2)

Pulling it together,
3x -19 = x + x +2
collect like terms
3x - 19 = 2x + 2
Put all the constants on one side by adding 19 to both sides.
3x - 19 +19= 2x + 2 + 19
3x = 2x +21
Subtract 2x from both sides to have all the x's on one side.
3x - 2x = 2x +21 - 2x
x = 21
The other number is 21 + 2, or 23
Check:three times the smaller = 3 x 21 = 63
sum of the two integers = 21 + 23 or 44
is 63 at least 19 more than 44

Luke wants to find the difference 175 - 134. He has subtracted the hundreds and tens so far. What is the sum of the two numbers he has subtracted? How much does he still need to subtract?

SUM means adding not subtracting. so if you were wanting to add the total (the sum) of the amounts of the hundreds and the tens would be 170 plus 130 which would be 300 but the remainder from subtracting 130 from 170 would be 40. That would leave the single units 5 minus 4 of which the remainder is 1. So, the remainder from subtracting 134 from 175 is the reminder of subtracting the one hundred from the one hundred which is zero added to the remainder of subtracting the tens (70 minus 30) which is the remainder of 40 plus the remainder of subtracting the units of 5 minus 4 which is 1. So you need to add the 0 and the 40 and 1 which is the remaining sum of 41.

How to find the mean absolute deviation

Add all the numbers together to get the sum.
Divide the sum by the number of numbers to get the mean.
so you have
1,2,3,4, that is 10. divide ten by four. because there are 4 numbers.
you get 2.5. Take each number and subtract 2.5. Discard all the negatives from the pile. So in essence you are taking the above example and subtracting 2.5 from 3 and 4 because the other two are going to be negative. so the answer is 3 - 2.5 and 4 - 2.5 which is 2. then take that 2 and divide by the number of items that you subtracted from which is 2. 2/2 is 1. one is the mean standard deviation.

Hi there, i have the same problem with the Casio fx 83ES. Simple Sums difficult without Exp?

The Enter Exponent key may be marked as x10^x. It is in the last row of keys, near the =/EXE. To enter a negative exponent use the change sign key (-), not the minus key for subtractions.

Find the sum of all countig numbers from 1 to 10000.

The sum of the first 7b8b965ad4bca0e41ab51de7b31363a1-1.gif counting numbers 1 + 2 + 3 + 4 + 5 +... + 7b8b965ad4bca0e41ab51de7b31363a1-1.gif is given by ef63e502172134f88498b84124306740-1.gif
Use 954cef9ef0a9ac7b6dd3277568558f47-1.gif, where 027c3429f98f7c39bab027549e1b9c7b-1.gif is the first term in the series, and 825b3fd5bafbc46b9a560ea9f16b21dd-1.gif is the last.

Now to solve this for nos, 1 to 10000 inclusive

Subtract 10000 - 1 = 9999 and add 1 to get 10000 terms in the series.

S = (10000[ 1+10000])/2 = 50,005,000.

This should do it.

Step1. Start Microsoft Excelmag-glass_10x10.gif and open the file you want to change. Step2. Double-click on the cell where you want the total to appear. Step3. Press the = key on the keyboard. This tells Excel that you are entering a formula into the cell. Step4. Enter the formula, then press Enter. Follow the steps below for an example. Step5. Enter an opening parenthesis character: (. Step6. Enter a cell name. For example: =(E2. Step7. Press the + key. Step8. Enter another cell name and a closing parenthesis character: ). For example: =(E2+E3). Step9. Enter a minus sign and a third cell name. For example: =(E2+E3)-E4. Step10. Press the Enter key to accept the formula. The cell will display the sum of the first two cells minus the third cell. $('.Article .Steps .Image').each(function(i,e){ e = $(e); e.find('img').error(function(){ $(this).unbind(); e.remove(); }); });
Tips & Warnings
  • Formulas are just equations. Instead of adding or subtracting numbers you are adding and subtracting the contents of a cell.
  • Excel includes a number of predefined functions to use as well. You can combine the predefined functions into your own formula. (See "How to Use Provided Excel Formulas.")
I hope it helps!!!

Sorry, I don't clearly understand what you want to do, but if you can explain a little more, I can help. If you want to subtract one cell from a column total, sum the column and subtract the one cell. If there is a need to subtract adjacent column entries, or similar type needs, there are formulas that can do this easily as well. Just a little more info - we'll have a FixYa!

Dear pauline, you can link cells in formula bar to see immediate effect of additions and subtractions in dependent boxes.

Like for example you add three numbers in three boxes A1, B1, C1 and answer is supposed to go in D1, just type =SUM(A1+B1+C1)
in D1.

now when you will change the values of a b and c boxes, the value of d1 will automatically change. for adding more numbers you can leave boxes empty so that you can fill in later to see the change in the sum box.

please press fixya if that has helped you.
