Universe Size Comparison vs DragginMath

Universe Size Comparison is a unique 3D astronomical app that will make you understand the real dimensions of the universe and how small we are. Have you ever wondered how big the Sun is compared to Earth? Or what is the largest planet between Mars and Earth? Do you want to find out the dimensions of some of the most famous stars in the sky like Rigel and Betelgeuse in comparison to our Sun? Do you want to compare everything with the hypergiant star VY Canis Majoris? Universe Size Comparison is the right app for you. The app offers two modes: Tour Mode and Free Mode. Tour mode will guide you on a spectacular journey where you will see planets and stars compared in full scale. All accompanied by simple and clear explanations regardless of the level of knowledge of the subject. The Free mode will allow you to compare two celestial bodies of your choice in scale. You will also find out more information on the bodies you are comparing thanks to an elegant user interface designed to offer the maximum user experience.

DragginMath is a new way to teach, learn, and do algebra. This app converts equations into interactive pictures. Get serious about math: turn equations into playthings! Yes, it's fun, but this is definitely not a toy. See the internal structure of equations. Then commute, associate, distribute, factor, simplify, and solve by dragging math under your fingertips. This is real algebra, not something that sort of looks like it. Not a function-graphing app. Not restricted to a few limited examples or prepared problem sets. This app can do an astonishing amount of symbolic math, but it is aimed at the algebraic novice. Do you or your students need help understanding the order of operations? Unsure what the various algebraic properties are or how to use them? Is solving an equation just some arcane mystery? DragginMath lets you see and experiment with symbolic math concepts. You still have to direct the work yourself, but without burning through erasers or reams of paper, and without needing someone to check your work. DragginMath is not curriculum. It is a tool, and it is curriculum-independent. If your textbook has expressions and equations in it, DragginMath can help you teach it, or learn it. You might even enjoy doing it. Are you a teacher? Create animated lessons just by using the app as you normally would. Add annotations and homework problems, then email them to your class within the app. Students watch your lessons, do their homework, and email it back to you within the app. Returned homework is formatted for easy management.
