# Arithmetic Questions

#### Arithmetic Questions allow you to assess students’ knowledge and comprehension of mathematics and number theory.

The following links will assist you in creating more math-focused questions within the HTML editor

Add new questions by accessing one of the following:

#### Through the Question Library:

- Select
**Assessment > Quizzes**from the course navbar. - Select
**Question Library** - Click
**New**. - From the drop-down menu, select
**Arithmetic Question.** - Enter a
**Title**(optional),**Points Value**(mandatory), and**Difficulty Level**(optional). - Enter your question into the
**Question Text**box. Enclose all variables in { } brackets.*Example:**Observe the following statements:**1. The probability of it being a sunny day tomorrow is {a}%**2. The probabilty of it being over 25 degrees is {b}%**3. The probability of it being both sunny and over 25 degrees tomorrow is {c}%**What is the probability that it is either a sunny day or over 25 degrees tomorrow, but not both?*

- Click
**Insert an Image**to browse through your computer to accompany your question with an image. Add a**Description**to the image (optional). - Enter the
**Formula**computed to get the solution to the question, enclosing all variables in { } brackets.*Example: {a}+{b}-{c}*

The following commands are recognized in the Formula box:

+, -, *, / | Basic Arithmetic Operators |
% | Modulo/Remainder Operator |

{x}^{y} | x to the power of y |
sqr({x}) | Square Root of x |

abs({x}) | Absolute Value of x |
sin({x}) | Sine of x (in Radians) |

cos({x}) | Cosine of x (in Radians) |
tan({x}) | Tangent of x (in Radians) |

log({n}) | Log Base 10 of n |
ln({n}) | Log Base e of n |

atan({x}) | Inverse Tangent of x |
sec({x}) | Secant of x |

cosec({x}) | Cosecant of x |
cotan({x}) | Cotangent of x |

Factorial({n}) | Factorial of n (n!) |
exp | The Power of Natural Log (e) |

pi | pi 3.14159 (accurate to 50 decimal places) |
e | e 2.71828 (accurate to 50 decimal places) |

- Select the number of acceptable decimal places for the solution entered under
**Answer Precision**. Select**Enforce Precision**if answers must be entered with exactly that many decimal places.

##### NOTE: If you Enforce Precision, be sure to mention in the question how many decimal places are expected in the answer.

- Select the number of units or percentages up or down the answer given can be from the correct solution under
**Tolerance**.*Example: A tolerance of +/- 2% would allow answers to be off by 2% of the correct solution. A tolerance of +/- 0 units would enforce answers to be exact to the correct solution.*

- Enter the unit type under
**Units**if you want it to be included in the answer (optional). Select the percentage of the grade of the question that is awarded for having the correct unit type. - For each variable you inputted in { } brackets in the Question Text box, click
**Add Variable**, enter the variable**Name**(as it appears in the Question Text box, but without the { } brackets), minimal value (**Min**), maximal value (**Max**), and number of**Decimal Places**for that variable. During a quiz, SLATE will then replace each variable in the { } brackets in the question with a random value between the minimal and maximal values you inputted, and compute the solution using these values and the formula you inputted. - Input the
**Step**that each variable may take between it’s minimal and maximal values.*Example: if the minimal value is 20 and the maximal value is 50 for variable a with a step of 5, variable a could be 20, 25, 30, 35, 40, 45, or 50.*
