A student writes [tex]$5y \cdot 3$[/tex] to model the relationship of the sum of [tex]$5y$[/tex] and [tex]$3$[/tex]. Explain the error.

So,
5y*3 is the open phrase the student uses to model "the sum of 5y and 3".
"The sum of" means addition. The student put 5y*3, while the sum of 5y and 3 is actually 5y + 3.

5y*3 This models the relationship as 5y times 3
But the question says to model the relationship as 5y plus 3.
Therefore, the right answer is 5y+3

The student incorrectly wrote 5 y ⋅ 3 when they intended to express the sum of 5 y and 3 . The correct expression for the sum is 5 y + 3 . This error highlights the importance of distinguishing between addition and multiplication in mathematical expressions.
