of a book I borrowed from the library.
The name of the book is "Arithmetic: The Easy Way" by Edward Williams and Katie Prindle.
I checked out the 1996 version (which is the only version my library has) of the book.
I'm on chapter four (which is a chapter on basic multiplication) and got all the questions right on the pre-test accept the geometry type questions.
I'm stuck on the part where it explains about the perimeter of a regtangle (2L + 2W). I understand the forumla,but only halfway understand how to write a shape / problem into a formula.
Here is the question:
"Write a formula for the perimeter of this triangle (it shows a picture of a triangle with two a's (on the right and left sides) then a b at the bottom). Complete the formula, writing it in its simplest form as was shown earlier." - pg.119 chapter 4
I just need similar problems like this to practice with. The thing about the book is that it only has one problem like this. Are there any other books / websites where I can get similar problems like this?
Sorry if the post is too long,
Thanks,
RB
