For every student who uses an easy to use online teaching tool to study online called XYZ Homework, it is a must for you to know how to use XYZ Homework. These followings will uncover about entering answers and the preview button. Please read everything well and if you need, you can also write down the important information on a piece of paper.

It is important for you to input your answers correctly when completing assignments in XYZ Homework. The reason why it is important is because it is useful to help the system determine their accuracy. There are a total of two ways to enter answers. The first one is by calculator style math or ASCII math reference on the inside covers and the second one is by using the MathQuill equation editor.

MathQuill is the one that allows the students to enter answers as correctly as displayed mathematics. Generally, when you click in the answer box following every question, there will be a yellow box with an arrow showing up on the right side of the box. By clicking this arrow button, you will be allowed to open a pop up window with the MathQuill tools for inputting normal math symbols.

### Preview button:

Beside the answer box, usually, there will be a preview button. Clicking this button makes the system display how it interprets the answer keyed in. It should be noted that the preview button is not grading your answer. This one is just indicating if the format is correct.

### Rationalize the denominator in the following:

√a – 1/√a  + 1 = (a-2 sqrt(a)+1)/(a-1)

Preview: a – 2√a + 1/a – 1 x syntax ok

Tips:

Tips are the ones that will indicate the kind of answer the system is expecting. Please pay extra attention to these tips when entering fractions, mixed numbers, and ordered pairs.
