This would just include one number in the question, which would not make a product.
3 less than the product of 9 and a number
5-3(6)
4 x 3 = 12. Therefore, any number less than 12 is less than the product of 4 and 3.
3x - 10
negga 5x - 3
15
13n - 3
-1
-3
3x - 3
It is 3n - 5.
1 * (1-4) = 1*(-3) = -3
