Numeric entries can be read by the system in the following styles:
-
Optional thousands separators can be used, so that 1,234 and 1234 will both be accepted.
-
Dollar signs will not be accepted in your answers.
-
You can use scientific notation in your answer, for example 2.37E-3 in place of 0.00237.
-
You can enter arithmetic expressions for your answer. For example if you enter 2.35+0.11 the system will grade it as though you had entered 2.46.
-
Negative numbers are denoted with a minus sign. For example, -27.5.
