Question

If there is no number before a variable, is there a coefficient and what would it be?
A. 0
B. 1

Answer 1

If there is no number before a variable, the coefficient is understood to be **1**. So the correct answer is **B. 1**. For example, in the expression \( x \), the coefficient of \( x \) is 1, meaning it can be interpreted as \( 1x \).
