Re: identify wheather the equation is true,false or open sen

32+5=6*6

x/17=-3

4*20=80

32+5 = 37
6*6 = 36
That one looks false.

x/17 = -3
That one looks Open

4*20 = 80
80 = 80
That one looks true.

You don't have these definitions in a book? No one ever explained what "=" means?

These are all very straightforward. You know how to add and multiply, and you have the definition (from your book and/or your class notes) for an "open sentence". So where are you stuck?

Please be specific. Thank you.
