Rounding off numbers is an important skill to learn for mathematical equations and real life problems. Although rounded numbers are less precise than non-rounded numbers, they’re easier to work with and better for visualising in your mind. You can round whole numbers, decimals, and fractions by remembering a few key tips as you do your equations. You can also use your calculator or an
The most common formula for the area of a square is simple: it's the length of the side squared, or s. But sometimes you only know the length of the square's diagonal, running between opposite vertices. If you've studied right triangles, you can find a new area formula that uses this diagonal as its only variable.
Geometry is the study of shapes and angles and can be challenging for many students. Many of the concepts are totally new and this can lead to anxiety about the subject. There are a lot of postulates/theorems, definitions, and symbols to learn before geometry begins to make sense. Through combining good study habits and a few study pointers, you will have success in learning geometry.
A prism is a solid, multi-sided geometric figure with two identical ends called bases. To find the volume of a prism, first calculate the area of one of the bases, then multiply it by the height of the prism. You can choose either the top or the bottom base since the bases are parallel and congruent polygons, or identical 2-dimensional shapes. Volume is measured in cubic units — don’t
Math is an engaging, rewarding field to study, although it also presents plenty of challenges. If you’re struggling with math—whether in or out of a classroom setting—there are plenty of concrete steps you can take to boost your math abilities. If you’re a student, don’t shy away from asking your instructor for help, and practice good classroom habits like taking notes and asking
A part of basic arithmetic, long division is a method of solving and finding the answer and remainder for division problems that involve numbers with at least two digits. Learning the basic steps of long division will allow you to divide numbers of any length, including both integers (positive,negative and zero) and decimals. This process is an easy one to learn, and the ability to do
How do you change those funny numbers and letters to something you or your computer can understand? Converting hexadecimal to binary is very easy, which is why hexadecimal has been adopted in some programming languages. Converting to decimal is a little more involved, but once you've got it it's easy to repeat for any number.
You probably hear all the time that you should check your math work. How to do that, however, might not be clear. There are a number of ways you can check the solution to your math work, depending on whether you are completing basic arithmetic problems, algebra, or word problems.
A box and whisker plot is a diagram that shows the statistical distribution of a set of data. This makes it easy to see how data is distributed along a number line, and it’s easy to make one yourself!
Calculating square root is easy if you have a perfect square. If you don’t, there’s a logical process you can follow to systematically figure out the square root of any number, even if you don’t use a calculator. You will need to understand basic multiplication, addition, and division first, though.
