Finger Math: Mental Math Tutor

Finger Math turns mental arithmetic into something you can see and feel. Learn a simple finger-counting method to add and subtract numbers from 0 to 199 using nothing but your two hands — no calculator, no paper, just practice that builds real mental math skills. WHAT YOU LEARN • Represent any number from 0 to 199 on your two hands — ones on the right, tens on the left, and the front of your left hand for the hundreds • Addition, subtraction, and mixed-operation problems • Step-by-step counting sequences that show exactly how each digit is formed, including carrying and borrowing HOW IT WORKS Progress through 15 structured levels, each with its own number range and difficulty — from single-digit sums up to the Mastery tier, where totals climb past 100. Every problem can be expanded into a clear, illustrated counting sequence, so you understand the method, not just the answer. PRACTISE WITH QUIZZES Test yourself with timed math quizzes in three formats: • See hands, choose the number • See a number, choose the hands • See hands, choose the matching hands Earn star ratings based on your score, track your best results and fastest times, and review the questions you got wrong.
