Multiple equations without calling them out
929236
This is a great way to introduce young children who likes math to the concepts of solving out multiple unknown variables in multiple equations.  My eight and seven years old loved it as a game.

Would be much better if you were able to use all of these signs at once instead of them being two sided.

I really enjoyed using these books. I always had trouble with Algebra until I learned the answer is always jesus. In real math problems like this x2 + 2x  3 are hard but in christian math it's easy the answer is always Jesus did it.

There's no 2D Mode. This means no exact answer in equation menu ( i.e : x =2 will give you 1.414... and not sqrt(2). Not really a problem in this case but clearly not ideal when trying to solve 4x^3 + 12x^2 + 27x + 39 = 0 ). Besides CASIO has blocked the OS-flashing that was possible on all previous versions, making this clearly not as versatile as before. A few years back, every casio calculator from the FX-92 had this 2D display and I was led to believe this one did also. It seems you have to get the "Power Graphics 2" model to have it.

this book was a great help in my differental equations class, it porvided a different explanation about the method of solving the differential equation. but i mostly used this book for the extra problems to reenforce the different methods of solving the diff. Eq. this book helped me to get an A in the course.  i could not give this book a bad revew because of all the help it gave me.

Es un libro muy bueno, si te gustan las matemticas lo disfrutars al mximo. Te ensea a ver las matemticas de una nueva forma muy apasionante e interesante. Recomendado al lim x->0 (1/x)

People learn in many different ways and my way is to know exactly what is going on in the problem and why the equation took that next step. Many of the problems in the book do this but there are a nagging few that do not show what formula they used. Of course the skills are built upon each other and it assumed that you remember the past formulas. For me though this doesn't always work out.

It is a great outline for those who need to brush up on their skills and it also helps out the beginners. Take lots of notes and remember the formulas to help out in later chapters. For the price it is a great help and I am happy to have made this purchase.

I hate statistics, but this book made it impossibly easy to understand. I actually got an A in the class and I took college Algebra and barely passed with a C. Really recommend the use of this text for those of us that are a little more mathematically challenged.

I like that I can switch between having the indoor temperature big and the outdoor temperature small or vice versa.  The one small problem I have with it is that in certain lights the numbers are hard to read.  Twos, threes and zeros sometimes look like eights, but if I stand at just the right angle I can make out what the number really is.  It would not stop me from buying this product again.  In fact I already had one of these myself, and got this latest one as a gift for a friend.

I was not allowed to have a graphing calculator on my math tests so I had to get a cheap scientific calculator to use.  This fit the bill.  Would buy again because it's well worth the cost for the capable unit you receive.

You cannot understand this book alone.  Only after reading his first two.
More towards the advanced practitioner, but it does provide many equations nonetheless.

The symbolized math equations and expressions are represented as pixelated images rather than some True Type font. The regular text is True Type and is easy to read. THE EQUATIONS ARE NOT.

I even installed Kindle for desktop and used magnification-- still very unclear.

Further, it appears returns or exchanges are not available for digital downloads.

I have a math brain. My daughter has a degree in actuarial mathematics. You can quantify the "conversion chart" by using the number 7 for remembering both combinations. We have successfully locked ourselves out of 2 of the 6 that I purchased and we can't figure out how we did it. We think we messed up by turning the screw at the wrong time, therefore changing the combination and here we are. Thank goodness we had not placed the keys in them yet. Customer service was very helpful in reviewing the instructions with me and I it sounded like they have done this quite often. Materials and construction are as stated, good quality. Using one lock would probably be easier than trying to remember and or log multiple codes and to match those codes to so many locks. To confusingly simple.

Really basic algebra and geometry. Not regular basic math at all so it won't work for us.

This is a good textbook with many solved and unsolved problems. I like the fact that it have many examples (one of the final chapters is applications of linear algebra to various fields) without sacrificing mathematical rigor (at the degree it is needed in an undergrad textbook). I didn't like the way it presented bases, spans, domains etc, I thought it was a bit stiff, but this is totally subjective.

I'm not really up on algebra, but this makes it easy.

This is an important book, but it would be more useful if it didn't have so many errors in the equations. Chapter 5, for example, states that the rates are a part of the model, but the equations on pages 210-213 only define the rates, but never use them. Equation 5.2-11 should have det(Cbar) in the numerator. There are many more errors like these in just the MLANS description in Chapter 5.
