Yearly salary - per workday pay equivalents

How much are you paid for each workday at different salary levels?

A $50,000 per year salary translates to $192 per workday.

To calculate this, I took 50,000 ÷ 52 weeks ÷ 5 days. A simplified way to do this would be 50,000 ÷ (52×5) or 50,000 ÷ 260. In essence, people with standard five day work weeks are working about 260 days per year. 

$60,000/yr = $230/workday

$70,000 = $269

$80,000 = $307

$100,000 = $384

$120,000 = $461

$150,000 = $577

These daily pay rates do not factor in the added value of 401K matching, health insurance benefits, and other benefits paid by the employer.

What size memory card to use for a Nikon D300?

If you're shooting RAW images with a Nikon D300, the NEF format raw files made by the camera average about 10.7 to 11MB each.

For an 8GB card (which really holds 7.4GB of files) see [Hard Drive Size Capacities Calculator] to learn why
7,400MB / 11MB per image
= 672 images per card

For a 16GB Card (which really holds 14.8GB)
14,800MB / 11MB per image
= 1,345 images per card

On an actual memory card from a D300, 6.9GB of space was used and held 643 images.  That averages to 10.7MB per image.

How to Add Consecutive Numbers

How to Add a Consecutive Series of Numbers in Your Head - wikiHow

* Think of the first and last number as a "stacks" that you add together. The second number and the second-to-last number will also equal the same sum.
To add 1-10:
10 + 1 = 11

Then divide the last number in sequence by two
10/2 = 5

Take these two numbers and multiply them to get the answer.

= 11 x 5
= 55

Adding 1-100
1 + 100 = 101 is the same as 2 + 99 = 101

- Add the first and last number together in the sequence.
- Divide the last number by two

1-100
101 x 50 sets = 5050

1-1,000
1001 x 500 = 500,500

1-1,000,000
1,000,0001 x 500,000 = 500,000,500,000 (500 Billion, 500 thousand)

Math Formula:
Here's another simple way to sum up a series of number. Use the mathmatical formula sum(n) = ( n * (n+1) ) / 2 - Check - This will work only if you want to add numbers starting from 1 and upto n.
