There is an a very easy way to do this if you have an access to the internet. Log on to www.blocklayer.com and click "General cals" then "Baluster stud+fence". Make sure you click the "English" just underneath. Then just type in the measurements.
To calculate 10% of anything, just knock off the right hand digit: eg 10% of 2354760 is 235476. You may have to put in a decimal point.
See the related links on how to calculate standard deviation. If there are more than a dozen data points, it is tedious to calculate by hand. Use excel or an online calculator. To get 2 standard deviations, multiply the calculated std deviation by 2.
To quickly calculate math problems that would (based on opinion) take too long to do by hand. It's very useful when you're doing algebra. It's just a modern convenience. :)
Some square roots can easily be calculated by hand. For example the square root of 4 is 2 and of 9 is 3. However, most of them are irrational which means that cannot be put in the form p/q where p and q are integers and q is not zero. So how do we find real numbers by hand that are irrational? The best we can do is to approximate them. There are many ways to do this. I will give you a link to a Wikipedia article that lists these:
The average velocity in a particular direction = distance travelled in that direction / time taken. Velocity is a vector so the direction is important. If I go from A to B and then return to A my average velocity will be zero. My speed, on the other hand, will not be zero.
Muscle of the hand.
This depends on ones skill; but the easiest technique for a do-it-yourselfer is to set the handrail in place first. Spindles or balusters with square stock on both ends would do best. Place the spindles, usually two per step, so they will be spaced evenly from step to step. Scribe a line on the upper square stock of the spindle from under the handrail. This will give you the angle of cut for all spindles; but you should check to insure that all lengths are the same. Even a 1/16th of an inch will make a difference in the spacing of spindles. Set the bottom square stock to the step or tread. Drill a pilot hole with a countersink drill into the upper square stock into the hand rail. Insure that this pilot hole is drilled on the upper side of the staircase. I would recommend a #8 countersink drill and #8 screws, at least 2" in length. Continue up the staircase and good luck. Enjoy your great job.
I call it a bannister if it is an indoor one. Outside is just a hand rail or railing.

The exact number is not possible to derive without knowing the average spacing of the hand holders.
Normally about 36-42 inches, but the safest bet is to check with the county to find out the exact requirements for where you live.
In the spacing between the frets on a fretboard. The closest fret to your finger between you and your left hand is the fret you are pressing.
You do not double space between words in your writing assignments. Always use single spacing between words unless the instructor states otherwise. On the other hand, while most writing assignments will use double spacing between lines, the instructor may demand that you use single spacing.
A set of railings can be also called bannister or blausters. A railing is traditionally used with stairs to provide a hand rail for support in walking up the stairs.

Yes, in most areas, you will need a permit for installing hand railings on a porch. Permits ensure that the railing meets local building codes for safety standards and dimensions. Check with your local building department for specific requirements and to obtain the necessary permit.
When using a computer or wordprocessor the left-hand margin is usually justified, which means that every line (unless indented) starts at the same distance from the lef-hand edge of the page. One can also justify the right-hand margin, but note that this can result in awkward spacing.
