If the number is n, and the product is of the numbers p and q, the expression is
p*q + (n + 15) : the parentheses are not necessary.
15 * 2, the product of 15 and 2, is 30And the product of 15 and 25, is 375And the product of 15 and 178, is 2770
Product means multiply in maths. 12*15=180
one number will be added
9x+7
The number are coprime so their LCM is their product ie 15*23 = 345
15 * 2, the product of 15 and 2, is 30And the product of 15 and 25, is 375And the product of 15 and 178, is 2770
Answer
the product of 15 and a number by its self four times.
Product means multiply in maths. 12*15=180
15
it is the number such that 15 added to negative 15=0
one number will be added

How about: 3*5 = 15 as a product of its prime factors
* n=15
It is 4n - 15.
It is 15 + 1x.
