In the last article, we applied our knowledge of fractions to begin making sense of percentages, and we used this new tool to quickly and easily calculate how much to tip at restaurants…all in our heads! Today, we’re continuing our exploration of percentages by using the power of 10% to quickly calculate how much money you’ll save the next time you go shopping for sales.But first, the podcast edition of this tip was sponsored by Go To Meeting.

For example, what’s 10% of $144? First, write the amount out with the decimal point and the digits representing the number of cents—like you’d see on a cash register: $144.00. Then, to find 10% of that amount, just move the decimal point one position to the left. So, $144.00 becomes $14.40 and, therefore, 10% of $144 is $14.40.If that makes sense, then you’re ready to move on. If you want a little more practice first, check out the practice problems from the end of the last article. And then be sure to catch the Math Dude Video Extra! episode on YouTube or Facebook to watch me solve the problems.How to Use Percentages to Figure Out How Much You’ll Save at a SaleOnce you can calculate 10%, figuring out how much you’ll save when things are on sale is easy. For example, say you’re looking at a sweatshirt that has an original price of $40, but is advertised at 30% off. What’s the new price? Well, just as with calculating tips in the last article, start by finding 10% of $40. Moving the decimal point one place to the left in $40.00, we find that 10% of $40.00 is $4.00. So,

Today’s article is about decimal points and numbers and how they’re related to fractions.But first, the podcast edition of this tip was sponsored by Go To Meeting.

And we’re all fortunate for that because it’s very convenient to work with. To illustrate this, let’s briefly talk about one alternative: the Roman numeral system. In this system, numbers are represented by letters: “I” = 1, “V” = 5, “X” = 10, “L” = 50, “C” = 100, “D” = 500, and “M” = 1000. To represent a number like 3, you write “III”; or to write 15, you write “XV”. We won’t go through all the details of how the system works—you can read about it on Wikipedia if you like—but the important thing to take away is that though this system is certainly a reasonable way to write and record numbers, it’s terrible for doing arithmetic. There’s just not a good quick systematic way to add a series of numbers like “XV + X + III + V”—and just imagine how hard it’d be to do division!Decimal IntegersHerein lies the beauty of the 0 through 9 number system—also known as the decimal system. (A quick aside: The word “decimal” here is derived from the same root word as “decade.” So just like there are 10 years in a decade, there are also 10 integer numerals—0 through 9—in the decimal system.) In contrast to Roman numerals, addition, subtraction, division, and many other things are all relatively easy with decimal numbers. This system allows us to write numbers using positional notation—that is, where the number of ones is represented b
