SOURCE: How do I solve an

If you do not have an ALPHA key you probably cannot use variable X. Besides, you are not solving anything here. You are merely adding two quantities. The problem is simple. You have solved countless number of similar examples where you were talking about concrete objects.

In algebra X (or any other letter symbol) is a place holder for any quantity you wish it to be. It could be apples, oranges, what have you. Using this analogy, ask yourself the question: 2 oranges + 8 oranges makes how many oranges. The answer is 10.
You will get the same value if instead of X=oranges, you have X=apples. So there is a universal truth and you state that by using an abstract entity called X.
Thus 2X+8X=10X. and X can stand for anything, anything at all.

### How do i get the ca756 to go to a power other than 2? I can get a number squared but not cubed or more.

there should be a button that has an x with a y where the two would be, i believe its above the delete button. that symbol is the same as x^2 (x Squared) except you input whatever you need to as the power in place of y. so hitting x^y followed by a 3 should cube your original x.
