Similar to what you see in your textbook, you can generally omit the multiplication symbol as you answer questions online, except when the symbol is needed to make your meaning clear. For example, 1⋅1051⋅105 is not the same as 11051105. When you need to be explicit, type * (Shift + 8) to insert the multiplication operator. You will see a multiplication dot (⋅⋅) appear in the answer box. Do not use the symbol ××. For example, for the expression mama, typing m ⋅⋅ a would be correct, but mxa would be incorrect. Enter the expression mama .
