Would you say that 3x can be thought of as three times a number?

anonymous · Answer

thrice a number, minus one

mathstudent55 · Answer

@thinker What's wrong with that answer?

anonymous · Answer

@mathstudent55 : yes , 3x can be thought of as three times a number.

mathstudent55 · Answer

@thinker 
You wrote "thrice a number, minus one"
The question is which answer is _not_ a way to say 3x - 1. Why are you saying that "thrice a number, minus 1" is not a way to say 3x - 1?

anonymous · Answer

@mathstudent55 : No, thrice a number, minus one IS actually 3x-1

The wrong one is - the difference of one and three times a number : coz it could also make it look 1- 3x
