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.

Put 70 in for F, and apply BEDMAS, the order of operations, brackets, exponents, division and multiplication, and finally addition and subtraction. In this case, we have to do the brackets first before the multiplication and division. The answer should be 21 degrees Celsius.

I'm assuming you mean the PEMDAS rule.

2 - 2 * 2 + 2

= 2 - 4 + 2

=-2 + 2

=0

The answer is 0.

2 - 2 * 2 + 2

= 2 - 4 + 2

=-2 + 2

=0

The answer is 0.

BEDMAS is a mnemonic device used to help you remember the order of operations in the evaluation of mathematical expressions.

B stands for Brackets OR Parentheses.

E stands for Exponent(iation)

D: division

M: multiplication

A: addition

S subtraction

I will amend the device to introduce the ROOTS, and to separate the levels of priority by --

B--ER--DM--AS

That means that raising to a power E and extracting a root R have the same priority. When these operations follow one another the order is from left to right.

Division and Multiplication have the same priority levels. When they follow one another, the order is from left to right.

How to use : RECURRENTLY

Look at the expression and locate the brackets (parentheses).

If there are many sets of parentheses start at the left and take care of the leftmost set. When inside the leftmost set of parentheses use B-ER-DM-AS again, and again until there is only one term left.

If there are embedded parentheses start from the deepest.

Let us simplify a bit.

**Inside first set of bracket**

Are there brackets: No

Are there Powers or Roots: yes. take care of powers and roots starting from the left until there are no more powers or roots

Are there multiplications or divisions? Yes. take care of multiplications and divisions starting from the left until there are no more divisions or multiplications.

The answer is 90. You must perform the operation in the following order: Multiplication and division first, then, addition and substraction as required.

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

The following are examples of expressions:

2

*x*

3 + 7

2 ×*y* + 5

2 + 6 × (4 - 2)

*z* + 3 × (8 - *z*)

Example:

Roland weighs 70 kilograms, and Mark weighs*k* kilograms. Write an expression
for their combined weight. The combined weight in kilograms of these two people
is the sum of their weights, which is 70 + *k*.

Example:

A car travels down the freeway at 55 kilometers per hour. Write an expression for the distance the car will have traveled after*h* hours. Distance equals rate
times time, so the distance traveled is equal to 55 × *h*..

Example:

There are 2000 liters of water in a swimming pool. Water is filling the pool at the rate of 100 liters per minute. Write an expression for the amount of water, in liters, in the swimming pool after*m* minutes. The amount of water added
to the pool after *m* minutes will be 100 liters per minute times *m*,
or 100 × *m*. Since we started with 2000 liters of water in the pool,
we add this to the amount of water added to the pool to get the expression 100 ×
*m *+ 2000.

To evaluate an expression at some number means we replace a variable in an expression with the number, and simplify the expression.

Example:

Evaluate the expression 4 ×*z* + 12 when *z* = 15.

We replace each occurrence of*z* with the number 15, and simplify using the
usual rules: parentheses first, then exponents, multiplication and division, then
addition and subtraction.

4 ×*z* + 12 becomes

4 × 15 + 12 =

60 + 12 =

72

Example:

Evaluate the expression (1 +*z*) × 2 + 12 ÷ 3 - *z* when
*z* = 4.

We replace each occurrence of z with the number 4, and simplify using the usual rules: parentheses first, then exponents, multiplication and division, then addition and subtraction.

(1 +*z*) × 2 + 12 ÷ 3 - *z* becomes

(1 + 4) × 2 + 12 ÷ 3 - 4 =

5 × 2 + 12 ÷ 3 - 4 =

10 + 4 - 4 =

10.

The order of operations of math is:

1. Parentheses

2. Exponents

3. Multiplication and Division

4. Addition and Subtraction

So for the problem you posted:

1. Remove the parentheses. The minus signs of -(-6) cancel and can be rewritten as +6. So the problem can be rewritten as 66+6x6+6.

2. Solve the 6x6 part first. Now the problem is 66+36+6,

3. Solve the arithmetic from left to right.

Therefore, the answer to your problem is 108.
