Texas Instruments TI30XIIS Blue Scientific Calculator

My daughter is quite happy to have it. Nice instrument.

Case is great, color is perfectly vibrant and all with TI reliability and teacher preference, you simply can’t loose with this one

This calculator is pretty durable. It reminds me of the calculators I used to use in high school. It's easy to use and it's got the basic functions necessary for my chemistry class. It's a little pricey for my taste, especially since you can find one for as little as $11 but the demand for this calculator is high and due to time constraints I had to settle for a higher price.

good value

It adds, subtracts, multiplies, and divides both integers and decimals with precision accuracy! It has lots of extra functions to keep parents amused while their child asks "hey, what does SIN do?" It's everything a parent hopes for when purchasing their child's first SCI Calc.Seriously though... Heading into her first year of Algebra, my daughter needed her first scientific calculator. This is the model they use in her class so I decided to get her one for home use. It's obviously not as full functioned as a full-on graphing calculator (I pulled out my trusty old TI-85 for comparison), but it's got everything she should need for the next few years of algebra and geometery. The solar cell works great on this. At night, indoors, the screen is still strongly visible and its nice not having to worry about batteries. This is a great tweener calculator.
