In a numerical input problem, learners enter numbers or a specific and relatively simple mathematical expression. Learners enter the response in plain text, and the system then converts the text to a symbolic expression that learners can see below the response field.
You can use this template as a guide to the simple editor markdown and OLX markup to use for numerical input problems. Edit this component to replace this template with your own assessment.
The system can handle several types of characters, including basic operators, fractions, exponents, and common constants such as "i". You can refer learners to "Entering Mathematical and Scientific Expressions" in the edX Guide for Students for more information.

= 100 +-5
You can use the following example problems as models.
>>How many miles away from Earth is the sun?||Use scientific notation to answer.<<
= 9.3*10^7
or= 9.296*10^7
[explanation]
The sun is 93,000,000, or 9.3*10^7, miles away from Earth.
[explanation]

>>The square of what number is -100?||Use scientific notation to answer.<<
= 10*i
[explanation]
-100 is the square of 10 times the imaginary number, i.

display_name:Numerical Input with Hints and Feedback
markdown:|
You can use this template as a guide to the simple editor markdown and OLX markup to use for numerical input with hints and feedback problems. Edit this component to replace this template with your own assessment.
You can provide feedback for correct answers in numerical input problems. You cannot provide feedback for incorrect answers.
>>Add the question text, or prompt, here. This text is required.||You can add an optional tip or note related to the prompt like this. <<
Use feedback for the correct answer to reinforce the process for arriving at the numerical value.
= 100 +-5 {{You can specify optional feedback like this, which appears after this answer is submitted.}}
You can also add hints for learners.
Be sure to select Settings to specify a Display Name and other values that apply.
Use the following example problem as a model.
>>What is the arithmetic mean for the following set of numbers? (1, 5, 6, 3, 5)||Use scientific notation to answer.<<
= 4 {{The mean for this set of numbers is 20 / 5, which equals 4.}}
||The mean is calculated by summing the set of numbers and dividing by n.||
||n is the count of items in the set.||
[explanation]
The mean is calculated by summing the set of numbers and dividing by n. In this case: (1 + 5 + 6 + 3 + 5) / 5 = 20 / 5 = 4.
[explanation]
||You can add an optional hint like this. Problems that have a hint include a hint button, and this text appears the first time learners select the button.||
||If you add more than one hint, a different hint appears each time learners select the hint button.||
