That looks like the description of an EXPRESSION. However, an expression need not have "at least one operation"; a single number, or variable, is a perfectly valid expression.

You have to assign some variable to "some number", for example "x". Then your expression becomes 12 / x.You have to assign some variable to "some number", for example "x". Then your expression becomes 12 / x.You have to assign some variable to "some number", for example "x". Then your expression becomes 12 / x.You have to assign some variable to "some number", for example "x". Then your expression becomes 12 / x.

17x+(1+x)
If x is the unknown variable then it can be: x-16

The number is called the coefficient of the variable
Let the number be x and so the expression is: x-19
It is the coefficient of the variable
Sample Response: Replace keywords with variables, numbers, and operations. “A number squared” is a power where the base is the variable and the exponent is 2. “Decreased by ten” means you must subtract 10 from the squared number.
