Astudent writes the difference between 15 and the product of 5 and y to describe the expression 5y - 15. explain the error

It is established that the statement 'product of 5 and y' is written as 5y. However, unlike addition and multiplication, there is no commutative property for subtraction. In other words, the order of numbers matter. Since 15 was mentioned first in the statement, the correct equation that should be formulated is: 15 - 5y.
