How it Works
### Stone and Mulch Calculators

As an example, let's use 500 square feet to be mulched at a

3" depth.

### For Your Information

3" depth.

- First, the depth must be converted to feet. To convert inches to feet, simply divide inches by 12, the number of inches in a foot.

So for our example: 3 inches divided by 12 equals a 0.25 foot depth. - Now that we have the depth in feet, we can multiply the depth by the area.

So for our example: 0.25 foot depth times 500 square feet equals 125 cubic feet. - If you are calculating 0.5, 2, or 3, cubic foot bags, simply divide 125 cubic feet by the size of the bag.

So for our example: if we are using 2 cubic foot bags, we can divide 125 cubic feet by 2 which equals 62.5 bags. - If you are calculating cubic yards, we need to convert 125 cubic feet to cubic yards by dividing by 27. One cubic yard is equal to 27 cubic feet, see the diagram below.

So for our example: 125 cubic feet divided by 27 equals 4.63 cubic yards.

- 1 inch equals 0.08333 feet
- 1.5 inches equals 0.125 feet
- 2 inc

Use the rules for exponents and you will calculate it by hand

(1*10^-14)/(5*10^-12)=(1/5)*10^(-14+12)= 0.2*10^-2=2*10-3

To enter powers of 10 use the short-cut key [EE]

For example to enter 6.02*10^23 type in** 6.02* [EE] 23**. When you use the EE key, the base (10) should not appear.

(1*10^-14)/(5*10^-12)=(1/5)*10^(-14+12)= 0.2*10^-2=2*10-3

To enter powers of 10 use the short-cut key [EE]

For example to enter 6.02*10^23 type in

This calculator does not have a key that you can use to find the prime factor of an integer.

You can however use the calculator to find the factors

1.** If number is even divide it by 2**

Keep dividing by 2, while keeping track of how many times you divided by 2.

If you divided 5 times by 2 before getting an odd number, then your first factor is 2^5

2.**Now try dividing by 3**, keep track of the number of times you divided by 3 before you could not divide by 3 any more. If you divided 0 times by 3, your second factor is 3^0, or 1 and 3 is not a factor.

If you divided 4 times by 3, your second factor is 3^4

3.**Divide by 5,** until you can't any more. Keep track of the number of times you divided by 5.

4. Divide by all other prime numbers 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, etc. For each prime number, keep track of how many times you divided by it, until you could not any more.

**Example: 23100**

*Division by 2*

23100/2=11550 ---------> 1 division by 2

11550/2=5775 ----------> 2 divisions by 2

Note that 5775 is not divisible by 2.** No more divisions by 2. **

First factor is 2^2

*Division by 3:*

5775/3=1925 ----------> 1 division by 3

1925/3=641. 66667 Not an integer. No more divisions by 3.

**2nd factor is 3^1**

*Division by 5 (number ends in 5)*

1925/5 =385 -------> 1 division by 5

385/5=77 ----------> 2 divisions by 5 and no more (quotient does not end in 0 or 5)

**3rd factor is 5^2**

*Division by 7 *

77/7=11 --------> 1 division by 7, and no more

**4th factor is 7^1=7**

*Division by 11*

11/11=1

**5th factor is 11^1=11**

Assembling the factors 2^2, 3^1, 5^2, 7, 11

Prime factorization of 23100 is

**23100=(2^2)(3)(5^2)(7)11**

You can however use the calculator to find the factors

1.

Keep dividing by 2, while keeping track of how many times you divided by 2.

If you divided 5 times by 2 before getting an odd number, then your first factor is 2^5

2.

If you divided 4 times by 3, your second factor is 3^4

3.

4. Divide by all other prime numbers 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, etc. For each prime number, keep track of how many times you divided by it, until you could not any more.

77/7=11 --------> 1 division by 7, and no more

11/11=1

You didn't specify the make and model of your calculator, so I can't give you an exact keystroke sequence.

The calculator doesn't care whether a number is a whole number or not. Just do the division.

On most algebraic-logic calculators, to divide 5 into 0.45, press . 4 5 / 5 =

On an RPN or RPL calculator, press . 4 5 ENTER 5 /

On most algebraic-logic calculators, to divide 5 by 0.45, press 5 / . 4 5 =

On an RPN or RPL calculator, press 5 ENTER . 4 5 /

If you still have problems, please reply to this post specifying the make and model of the calculator you're trying to use.

(2x3^2) divided by (2x3^(-2))

just make sure to use double parenthesis around the negative exponent so that you get the right answer

I would press 14 and then press the divide button and then press 10. That would give me 1.4 then i would press the multiply button and press 1 and the divide button and press 4, then i would press equal.

That gives me 0.35

That gives me 0.35
