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⋅105 is not the same as 1105. 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 ma, typing m ⋅ a would be correct, but mxa would be incorrect. enter the expression ma .

ma= ma

m⋅a = m⋅a

And equivalently:

am=ma

a⋅m = m⋅a

Question

Assuming this question "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*10^5 is not the same as 110^5 . 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 x. For example, for the expression ma,

typing m⋅a would be correct, but mxa would be incorrect".

Solution to the problem

For this case we want to write a expression for ma, and based on the previous info we can write:

ma= ma

m⋅a = m⋅a

And equivalently:

am=ma

a⋅m = m⋅a

But is not correct do this:

mxa=mxa

axm = mxa
