How do i make subtraction, additions and divisions using excell

Quick-Start Guide When you enter an expression into the calculator, the calculator will simplify the expression by expanding multiplication and combining like terms. At this point the calculator will attempt to factor the expression by dividing a G C F, and identifying a difference between two squares, or factorable trinomials. Use the following rules to enter expressions into the calculator. Variables Any lowercase letter may be used as a variable. Exponents Exponents are supported on variables using the ^ (caret) symbol. For example, to express x 2, enter x ^ 2. Note: exponents must be positive integers, no negatives, decimals, or variables. Exponents may not currently be placed on numbers, brackets, or parentheses. Parentheses and Brackets Parentheses ( ) and brackets [ ] may be used to group terms as in a standard expression. Multiplication, Addition, and Subtraction For addition and subtraction, use the standard + and - symbols respectively. For multiplication, use the * symbol. A * symbol is optional when multiplying a number by a variable. For instance: 2 * x can also be entered as 2x. Similarly, 2 * ( x + 5 ) can also be entered as 2 ( x + 5 ) ; 2 x * ( 5 ) can be entered as 2 x ( 5 ). The * is also optional when multiplying parentheses, example: ( x + 1 ) ( x - 1 ). Order of Operations The calculator follows the standard order of operations taught by most algebra books - Parentheses, Exponents, Multiplication and Division, Addition and Subtraction. The only exception is that division is not currently supported; attempts to use the / symbol will result in an error. Division, Square Root, Radi cals, Fractions Division, square root, radi cals, and fractions are not supported at this time. A future release will add this functionality.

that's all I can say basically I learned it this way.

I assume you mean (2x12)/4+10-6 as in your first post. I can understand how you got the wrong answer of 3 in that case but not as you wrote it here.

Multiplication and division get precedence over addition and subtraction.

First, evaluate the expression inside the parentheses: 2x12 is 24.
Then divide by 4 to get 6.
Add 10 to get 16.
Subtract 6 to get 10.

If you incorrectly do addition and subtraction before division then you divide 24 by 4+10-6 (which is 8) and get 3.

When you perform an arithmetic operation such as addition, subtraction, multiplication, or division the result has a specific name. The result of addition is called the sum; the result of a subtraction is called the difference; the result of multiplication is the PRODUCT. Finally the result of a division is the quotient.

You'll need to use the Order of Operations to solve this problem. They are Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction (Please Excuse My Dear Aunt Sally). Multiplication/Division have the same weight, so you read it from left to right. Same with Addition/subtraction.

For this problem, you see there are no parenthesis or exponents, so you move right to multiplication/division. Reading from left to right, the first thing you see is 240/20. Evaluating that comes out to 12. Now you have 12*6 (assuming the x is a multiplication symbol), which evaluates to 72. 72-13=59, and 59+41=100.

Written another way:
240/20*6-13+41
12*6-13+41
72-13+41
59+41
100

Shift + 8

did you say
6-(-9)=15
then it is true as negative multiplied by negative is always positive.
Also multiplication comes first than addition.
Hey, here is a FREE tip. Do you need to memorize the order of priority of these function then learn B O D M A S
(Bracket of Division Multiplication Addition Subtraction).

1. Make sure you have entered the numbers you'll need in necessary columns
2. Go to the column you would want the results to appear in
Guide: + (addition); -(subtraction); *(multiplication); /(division)
3. Type in =(select a cell)+ (Select the other cell) - (select the appropriate cell) and so on
4. If you are looking for a sum of try this formula, SUM=(select the first cell in the roll or column, hold the shift key and select the last number) then press enter

Any formula in Excel starts with the equals sign ("="). This is how Excel distinguishes between formulas and literal values. Knowing this, you can create lots of formulas using the usual operators of +, -, * and / for addition, subtraction, multiplication and division, respectively. Please see the examples below.

Add 1 + 1: =1+1
Add the contents of cell A1 to the contents of cell B1: =A1+B1

Subtract 2 - 1: =2-1
Add the contents of cell A1 from the contents of cell B1: =B1-A1

Multiply 1 times 2: =1*2
Multiply the contents of cell A1 times the contents of cell B1: =A1*B1

I hope this resolves the question. If not, please let me know.
