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.

Just want to make sure that we are on the same page.

2^(-3) + 3^(-3)

2 to the exponent -3 + 3 to the exponent -3

Because of BEDMAS, we have to do the exponent calculations first and then do the addition between the two terms last.

The rule of negative exponents is you put 1 over the base to the same exponent, but change the exponent from negative to positive.

=1/(2^3) + 1/(3^3)

= 1/8 + 1/27

To add or subtract numbers, we need a common denominator.

Let's factor 8 and 27 to get the lowest common multiple.

8 - 1 2 4 8

27 - 1 3 9 27

Nothing in common to eliminate, so we have to use 8 x 27 or 216.

27/216 + 8/216 = 35/216

Good luck,

Paul

You can view this question as what is the surface area of the 13 inch round pan, and then with it being 2 inches deep, calculate the volume.

Surface area = pi * r ^ 2, where r is the radius of the pan

In this case, the diameter is 13 inches, so the radius will be 6.5 inches.

Putting it into the formula, we get surface area = pi * 6.5 ^ 2.

Because of BEDMAS, we have to do the square before we multiply.

Surface area = pi * (6.5 ^ 2)

= 132.7square inches.

To get the volume, we multiply this surface area by the depth of 2 inches.

Volume = surface area * height

Volume = 132.7 * 2

Volume = 265.4 cubic inches.

Good luck,

Paul

Hi,

I assume 13m/2 is the radius of the sphere and you are trying to calculate the volume of the sphere.

The first thing we have to think of is BEDMAS, the order of operations, as some calculators do them correctly, while others do not. Let's be safe and do the BEDMAS manually so we know we will get the correct answer.

B - brackets - enter 13/2 in the calculator - hit enter

E - exponents - with the answer from the first line in the calculator, use the hat key (^) or the y to the x key to raise this to the third power (exponent 3).

M - multiply - with the answer from the line above, multiply this by pi or use what you are instructed to use or use 3.14159, then multiply by 4 and divide by 3.

You should have your answer.

Good luck.

Paul

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.

We have to follow BEDMAS, the order of operations, where brackets are first, then exponents, followed by division and multiplication, and finally addition and subtraction.

Also, we have to use the exponent law of an exponent to an exponent, we multiply the exponents with the same base.

If we forget this, we can always do it the long way.

(x^5)^3 = (x^5)(x^5)(x^5) = x^15

Similarly, (x^3)^4= (x^3)(x^3)(x^3)(x^3) = x ^12

Now that we have done the exponents, we can multiply x^15 by x^12 and get x^27.

Good luck.

Start by using the distributive property to expand the term 5(I-31)=5*I-5*31=5*I-155.

Rewrite the equation as 5*I+5*I-155=55

Combine the terms with I, this yields 10*I-155=55

Add 155 to both sides of the equation 10*I-155+155=55+155

you now get 10*I=210

Divide both sides of the equation by 10

(10*I)/10=210/10

Cancel the 10's on the left and divide 210 by 10 to get 21

Thus I=21

Basically you use the priority order of operations BEDMAS backwards
