In addition to those category-based collections, in the section below we offer a collection of some of the best math-related calculators from around the web. Here are our algebra, geometry, trigonometry, graphing, and calculus calculators. In addition we are constantly adding new calculators to our site. These would be a lot of fun for children just learning their facts to work independently, since the self-check is built in.We offer a free scientific calculator. Each of the three "calculators" looks nearly identical, but with a different arrangement of numbers. The only quirk is that the monkey's toes need to point to two different numbers, so you can't use these to multiply, add or subtract the same number from itself (like 12 x 12, 4-4 or 6+6). For example, if you position the monkey's feet over the 3 and the 10 on the Monkey Multiplier, then the number "30" displays in the ring in the monkey's hands. Move the monkey's toes to point to two numbers at the bottom of the board, and the ring held in his hands will highlight the answer to the math problem. The monkey's feet rest on the numbers 0-12 or 1-12 and his hands hold a ring that is positioned in front of the blackboard. In front of the blackboard is a three-dimensional monkey with hinged arms and legs. This unique way to practice and check basic math facts will be a hit for kinesthetic and tactile learners! Each one features a plastic board (8.5" x 11.25") with a design that looks like a blackboard, with a series of white numbers arranged in a triangular pattern.
