Seven increased by the product of a number and 2 greater than - 15
Use the variable c for the unknown number
The expression "a number" can be represented by the variable c.
The product of a number and 2 greater than -15 can be written as c * (2 + (-15)).
Since "increased by" means to add, "Seven increased by the product of a number and 2 greater than - 15" can be written as 7 + (c * (2 + (-15))).
Simplifying the expression:
7 + (c * (2 + (-15))) = 7 + (c * (-13))
Therefore, the expression "Seven increased by the product of a number and 2 greater than - 15" is equal to 7 + (-13c), or 7 - 13c.
