Glossary of mathematical symbols. A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula. As formulas are entirely constituted with symbols of various ...
List of mathematical symbols. The list below has some of the most common symbols in mathematics. However, these symbols can have other meanings in different contexts other than math. If x=y, x and y represent the same value or thing. If x≈y, x and y are almost equal. If x≠y, x and y do not represent the same value or thing.

strict inequality. less than. 4 < 5. 4 is less than 5. ≥. inequality. greater than or equal to. 5 ≥ 4, x ≥ y means x is greater than or equal to y.
Review the concepts of mean, median, and mode in statistics on Khan Academy.
- It is not possible to create a formula for the median, because the median value depends on the position of the middle value of the set and the fact...
- i am a teacher and it says sort the data from least to greatest in the quextion you need to arrange the values first than solve the answer will be 8
- Yep, you can just keep getting more and more negative.
- I believe you would list them both. So in your case, the modes would be 8 and 10 since they both occur at the same time. I hope this helps!
- Choose MEAN if you need the average and you are working with numerical qualitative values. Choose MEDIAN if you have outliers. Outliers impact the...
May 2, 2015 · But what does this say? I just want to understand some applications. NOTE: I'm still on integration by parts, so try to explain in simple terms. This site scares me sometimes... xD. Thanks! EDIT: I got the x-axis and y-axis mixed up when I wrote it. I do understand what they actually mean. Sorry!
Replace each variable in the expression with the specified value, and then simplify the resulting expression by specifying the order of operations. Example 1: Consider an algebraic expression x+5, Let’s evaluate it for x=7. Substitute the value of x in the expression. 7+5=12. Example 2: Consider an algebraic expression y2-5y+2.
