In this Education video tutorial you will learn how to perform short division. The first example is a division by a single digit; 741 divided by 3. You write it as shown in the video and start dividing from the left digit. So, 7 divided by 3 will give 2 with 1 as remainder. Write this down as demonstrated in the video. 1 and 4 make 14 and dividing 14 by3 will give 4 and remainder is 2. Now dividing 2 and 1, that is 21 by 3 you get 7. The answer is 247. The next example is 847 divided by 5. 8 ...
This video is about Level 2 atomic concepts, specifically the Pennium Lab. This helps you understand how atomic masses are derived for the periodic table. This teacher demonstrates how to do the calculation. He first reviews the Isotopes as they are different masses of the same type of atoms. He uses chromium as his example. It has a different number of neutrons in the nucleus. Using the equation, it could have either 26, 28, 29 or 30, with its 24 protons. So he subtracts the atomic number fr...
This video demonstrates the quotient rule as applied to exponential expressions that appear in the form of, to use the word loosely, a fraction. The name, "quotient rule", refers to the fact that it applies to expressions which are divided by other expressions. The video begins by explaining that the quotient rule allows expressions in this form to be simplified if they contain like bases (i.e., the terms are of the same variable). The quotient rule allows the expression to be simplified by s...

Firmly crease the fold. Fold the first corner to the line of the first fold made on the opposite side. Repe...
In this educational video the instructor shows how to find the slant asymptotes of rational functions. Slant or oblique asymptotes occur when the degree of the numerator is exactly one greater than the degree of the denominator of the rational function. The way to find the equation of the slant asymptote from the function is through long division. In this long division you divide the numerator with the denominator by following the long division method as shown in this video. Before dividing i...

Your first step is to bring your decimal point up to the top of the equation. The you divide the whole number into the decimal number. In this instance, 5 into 1.25. 5 goes into 1 0 times, so you put the zero in the first space. 5 goes into 12 twice, so you place a 2 up top, after the decimal. Then you subtract 10 from the 12 to leave you with a 2. This then gets added on to the 5, so you divide 2 into 25 giving you 5. So your answer is 0.15. You can then do this for any whole number and frac...

Apple doesn't include its Calculator app on the iPad and never did. One almost appeared over 12 years ago but was nothing more than a blown-up version of the iPhone app. Since then, the company still hasn't made an iPad-optimized calculator, and there is no shortage of third-party alternatives to fill the gap. It may happen one day, but for now, these are the best calculator apps for your iPad.

With HUP, any employee or student of an organization that has a Microsoft volume license is eligible to purc...
Hair products can work wonders, but the good stuff is usually super expensive. Plus, most of the major brands use a ton of ingredients you can't even pronounce, so it's safe to say a lot of us have no idea what we're putting in our hair. The good side is that most products can be made at home using basic ingredients for a fraction of the cost of commercial brands. Hairspray is no exception, and actually one of the easier ones to make.
