## Description

The best way to learn multi-digit subtraction. Handwrite answers. It teaches, tracks progress, and helps a child learn what they don't know quickly.

SUBTRACTION is a smart math app that teaches children how to subtract multi-digit numbers together. It monitors what the student knows and where they still need practice. It teaches step-by-step how to subtract small numbers and then progresses to multi-borrow subtraction. SUBTRACTION 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 3-1=2 to more difficult equations such as 904-795, 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 subtraction or a quick review for slightly older students.

Students practice writing numbers too. AI converts the student's handwritten numbers into digits. Single-digit subtraction is free.  Multi-digit subtraction with borrowing along with custom colors, specific numbers to learn, different character voices, and background music requires an in-app purchase.
