Bad formulation of task

I don't think it matters as long as it results in the value 10.

So ten = b + c + c should work but ten = b * c + b should also work.

You mean something like 3 * a ?

You're not allowed to use them for this exercise. You can't use any number literals. Only the variables and numeric operators.

As Jacob mentions, there's different ways to get the answer and they all should work as long as you only use what's allowed.

But what about coefficients? There are no information about using them.

2 Jason,

Exactly. Now it is clear, but I think it will be better to clarify for customer, that using of coefficient are not allowed, because formulation " using only variables a, b, and c and the common numeric operators" for me does not make clear, that coefficients are also not allowed.

In any case, thank you for great job. it is the best portal for learning I have ever seen.

Q: Create a variable named "ten" and assign the correct numeric value 10 to it using only variables a, b, and c and the common numeric operators.

Below is only calculate:

  var a = 1,
        b = 2,
        c = 4;

Then the answer is: Easy..!

  var a = 1,
        b = 2,
        c = 4;


  var ten=(b*c)+(b*a);
