If there is no number before a variable, the coefficient is typically assumed to be 1.
If there is no number before a variable, the coefficient is generally considered to be 1. However, it's important to note that in some cases, the coefficient may be 0. In algebraic expressions and equations, the coefficient represents the numerical factor by which the variable is multiplied. If there is no number explicitly written before a variable, it is generally assumed to have a coefficient of 1.
