And this one................

WebAssign will do simple calculations for you, using +, -, *, /, parentheses, and E-notation. For example, if a question asks for half the sum of 246 and 388, you can enter "(246+388)/2". For more complicated calculations you'll need to use a calculator and then enter your result. What is the product of 110 and 160?


Thanks,

Dude. In your house you have something called a computer. On it, your daughter can use something called the internet. On the internet there is a search engine called Google.

And if she's getting homework on this surely she was taught this in class?

r=(a^2+b^2)^0.5 or r=sqrt(a^2+b^2) will do it. And the second one...17600?

yes I do but its not just addition in this case

The answer is not 270
You don't know what a product is, do you?

Thanks you I will try these answers on the computer she is using.

This is something she got for extra credit over the summer.

It is one of those questions that you think it "can't be that easy". Rather then give the wrong answer , I figured I'd ask you smart YOUNG people.
