Numeric entries can be read by the system in the following styles:

• Thousands separators should not be used. Enter 1234 instead of 1,234.
• Dollar signs will not be accepted in your answers.
• Scientific notation may not be used. Enter numbers in decimal form like 0.0035, and not 3.5E-3.
• 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.
