Question

debbieg · Answer

If I said, "the sum of 11 and x", what would you write?

anonymous · Answer

x+11

debbieg · Answer

Good. 

Now, if I said, "the product of 2 and r", what would you write?

anonymous · Answer

2r im not sure

anonymous · Answer

2r im not sure

debbieg · Answer

Well, that's right - product is just muliplication, and 2r means "2 x r"

So you have that the product of 2 and r is 2r.

You know that the sum of 11 and {something} is 11 + {something}

So can you put all that together, and write an expression for "the sum of 11 and the product of 2 and a number r"?

@jenny01462  re-read what I wrote above and everything you've done. You're letting yourself be intimidated by this because you know it's "math". :) I'm telling you, you got this!

Just put them together.

The sum of 11 and {something} is

11 + {something}

Your {something} in this case is the product of 2 and r, which as you told me, is 2r.

I have faith! Try it.
