I just got the board this year and I can not find any information on it." ***FEATURED DISCUSSION Using Solver on TI-84 http://mathforum.org/mathtools/discuss.html?&do=m&thread=c__dd___g-1 Davem wonders, "Is there a way to store in memory the solution to an equation found using Solver, in order that it can be used in a follow-up calculation?" ***FEATURED DISCUSSION 24 Game in Excel http://mathforum.org/mathtools/discuss.html?&do=m&thread=m6__hif_tool__g-1 Don Link states, "Please take a look at my 24 Game implemented in Excel and give me any suggestions for improvement. Not only does it give random problems, it also displays all possible answers." ***FEATURED TOOL Tool: Geo-Calc BaldGeeks http://mathforum.org/mathtools/tool/25989/ Macintosh shareware for calculating the area, perimeter, sides, angles, and other measures of two- and three-dimensional shapes such as ellipses, rectangles, triangles, trapeziums, parallelograms, polygons, prisms, cylinders, cones, pyramids, and spheres. If entered values do not describe a valid geometrical figure, Geo-Calc highlights the specific problem and suggests solutions. Also available in German and Norwegian. ***FEATURED TOOL Tool: Let's Count! Jayzeebear.com http://mathforum.org/mathtools/tool/25922/ Click on the numbers and count the animals that are displayed. ***FEATURED TOOL Tool: Manny's Rumba The Learning Box http://mathforum.org/mathtools/tool/25920/ Given a target number in the form of an equation "Make x = (number) blocks," move the base ten blocks (ones or tens) to the area showing the target number. ***FEATURED TOOL Tool: Pythagorean Theorem Lesson Angie Brock http://mathforum.org/mathtools/tool/21673/ This interactive lesson (from eNLVM) compiles some of the resources found here in the Math Tools Digital Library and also off the Internet to teach about the Pythagorean theorem. Sections include Objectives, Introduction, Explore, Pythagorean Proof, Another Proof, Still Another Proof, Using the Pythagorean Theorem, Applications, Pythagorean Explorer, and Quiz. ***FEATURED TOOL Tool: XP Math: Comparing Fractions T.L. Hui http://mathforum.org/mathtools/tool/22429/ To compare fractions, you may either a) rewrite fractions with a common denominator, b) convert fractions into decimals, or c) compare their cross products. ***FEATURED TOOL Tool: Vehicle Routing Problem Applet DNS http://mathforum.org/mathtools/tool/23965/ An applet showing a solution of the Vehicle Routing Problem with Time Windows using a Genetic Algorithm. Demo of a JAVA-based library to perform tour scheduling and resource optimization tasks.
