The <strong>hypotenuses of these triangles slide along number lines</strong>, while their vertices are connected, forming a <strong>hinged rhombus</strong>. By placing the sliding points on different integers, the <strong>calculator determines the midpoint of these integers to display the results</strong>. This model is based on <a target="_blank" href="https://patents.google.com/patent/US1188490A/en" rel="nofollow noopener">the expired “educated monkey” patent from 1915</a>.</p><figure class="image image_resized" style="width: 77.87%"><img src="https://makerworld.bblmw.com/makerworld/model/DSM00000000510362/design/2024-06-23_64af858aedd67.png"></figure><h2> </h2><h2><u>Assembly Guide</u></h2><h3>Froggy Version:</h3><p>Step 1: Place the Screws, Feet, and Vertical Bar onto the Base.</p><figure class="image image_resized" style="width: 70.46%"><img src="https://makerworld.bblmw.com/makerworld/model/DSM00000000510362/design/2024-06-23_fa5748c5a3b0a.png"></figure><p>Step 2: Add the Legs.
