This modern marvel of calculator engineering by Texas Instruments is more than any student taking standardized tests could have hoped for before 2010. This calculator has a 3.2 LCD colored screen, 3D graphing, storage of up to 100MB, rechargeable battery, USB port, and is approved for major standardized testing! This calculator can store .jpg, .png and .bmp files making it the ultimate integrity test for any student looking for an edge. The calculator is currently selling for around $150 from Walmart, but with its "Solve" function that solves any equation put into it, it may be worth the price to someone looking for an easy A!
