Bar notation is a easier way of writing the same repeating digits or decimals after the decimal point. A bar notation shows that the number pattern goes on for infinity forever. Bar notation used for a repeating decimal, place the bar over the part of decimal that is repeating.
When to use bar notation?
Bar notation may only be used on a repeating number or series of numbers AFTER the decimal point. Using bar notation, which is a way to show repeating numbers after a decimal point, is easier than writing the same repeating number and over again.
How do you write 1/7 in bar notation?
Here's another example. 1 / 7 = 0.142857142857142857142857142857... But using bar notation, you would say 1 / 7 = 0.142857 with a line over those numbers to show that they repeat over and over. You can use the bar notation over any number that repeats the same number or numbers again after the decimal point.
What is the difference between bar and decimal notation?
See, it's a totally different number. Bar notation may only be used on a repeating number or series of numbers AFTER the decimal point. Using bar notation, which is a way to show repeating numbers after a decimal point, is easier than writing the same repeating number and over again.
How do you interpret a bar chart with no baseline?
A bar chart with a non-zero baseline or some other gap in the axis scale can easily misrepresent the comparison between groups since the ratio in bar lengths will not match the ratio in actual bar values. By cutting 90 points out of the vertical axis, a small 4-point difference can be exaggerated to look like a 1:3 ratio.

When you should use a bar chart
A bar chart is used when you want to show a distribution of data points or perform a comparison of metric values across different subgroups of your data. From a bar chart, we can see which groups are highest or most common, and how other groups compare against the others.
Best practices for using bar charts
First and foremost, make sure that all of your bars are being plotted against a zero-value baseline. Not only does that baseline make it easier for readers to compare bar lengths, it also maintains the truthfulness of your data visualization.
Common bar chart options
A common bar chart variation is whether or not the bar chart should be oriented vertically (with categories on the horizontal axis) or horizontally (with categories on the vertical axis). While the vertical bar chart is usually the default, it’s a good idea to use a horizontal bar chart when you are faced with long category labels.
Visualization tools
Most tools that can create visualizations, whether they be spreadsheets, programming libraries, or business intelligence tools, should be capable of creating basic vertical bar charts. Sometimes, options need to be checked or modified in order to follow best practices. However, for basic data exploration needs, any tool should be sufficient.
Forever and Forever
There is a symbol that stands for infinity. Infinity means that something goes on forever. For example, numbers go on forever. You can add 1 to any number to get a higher number. Look at the symbol and follow it around and around with your finger. You never get to the end of it. It goes on forever, infinitely.
Forever and Forever in Math
Sometimes in math there are numbers that go on forever. Most of the time, they repeat the same numbers over and over again. For example, some solutions for division equations go on forever. They repeat, and continue to repeat, on and on and on.
Writing Bar Lines is simple once you understand their function
Bar Lines are vertical lines in our music that have specific functions based upon how many of them are used and their “size” (thickness).
Writing Bar Lines – Where Do You Use Them?
Bar Lines are taught in the Prep 1 Rudiments Workbook on Page 32 and in the Basic Rudiments Workbook on Page 13.
Writing Bar Lines – How Do You Write Them?
On a single staff, Bar Lines are never written “outside” the staff. Bar Lines are written from the top of the staff (line 5) to the bottom of the staff (line 1). Even if the staff uses Ledger Line Notes, the Bar Line does not extend outside the single staff.
