Subtraction Mathematics

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, parent, and teacher 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: choose 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.
