ADDITION is a smart math app that teaches children how to add multi-digit numbers together. It monitors what the student knows and where they still need practice. It teaches step-by-step how to add small numbers and then progresses to multi-carry addition. ADDITION is encouragement-based providing positive reinforcement for the student's effort both visually and auditorily. The student, parents, and teachers can all quickly see where the student needs more practice in a color-coded format. Go from simple math facts like 0+1=1 to more difficult equations such as 345+789, with the app showing you the correct answer if you make a mistake. Full customization is possible including choosing the specific digit combinations you want to review or practice. Excellent for beginners just learning addition or a quick review for slightly older students. Students practice writing numbers too. AI converts the student's handwritten numbers into digits. Single-digit addition is free. Multi-digit addition with carrying along with custom colors, specific numbers to learn, different character voices, and background music requires an in-app purchase.
