Example 2: Currencies

Let us create a basic question with currencies:

As you have seen in the example involving units, you need to enable the currencies in Input options > Input syntax. Notice all currencies can be selected with only one box.

The algorithm is straightforward. Notice that if you want to make an algorithm for a question with currencies, you must use the corresponding CalcMe symbol under the Units of measure tab.

To conclude, currencies are similar to physical units, and we have to take into account:

• You can do basic arithmetic with currencies, unless convert() between them.
• Students can write the currency symbol at left ($12) or right (34€). Both styles will be graded as correct.
• Students must type the currency symbol using their keyboard. The toolbar for the answer doesn't have any currency symbols. So please ensure that students have the symbol on their keyboard! Alternatively, provide it in the question wording for them to copy & paste.
