Determine whether the following statement is true or false. In π plus 39, the variable π can have any value.

So, weβre talking about having π plus 39. But in fact, this could be any letter. So, it could have π plus 39 because the letter just refers to a variable and that variable can take any value whatsoever. So, we could have any value for our π or whatever letter we chose to put there. So therefore, weβve got the answer to the question cause we can say that the variable π can have any value. So, the answer is true.

Well, itβs worth noting that the reason that it can take any value is because itβs an expression. However, if we use this expression to form an equation such as π plus 39 equals 41, then to satisfy this equation, our π must take one value. And in this case, that value must be two. You canβt have equations where it has more than one value. However, when weβve got an equation, there would definitely be some specific values that it would have to take.
