Hissan Master is an iOS app for kids to practice written arithmetic — addition, subtraction, multiplication, and long division — in the same column format used in school. Choose from 1–3 digit numbers to match your level, and get instant feedback on every answer.
Practice addition, subtraction, multiplication, and long division — all in proper written format. Multiplication includes partial products for 2-digit × 2-digit problems. Long division walks through quotient, product, and remainder step by step.
Mix and match 1-, 2-, and 3-digit numbers to set the difficulty that's right for you. Start with 1×1 digit and work your way up to 3×2 digit problems as your skills grow.
Tap "Check Answer" and a big animated circle (correct) or X (wrong) appears right away. You can see immediately where you went wrong and try again on the spot.
Every tap of "Next Problem" generates a fresh random question within your chosen digit range. Endless variety means you'll never run out of problems to practice.

On the menu screen, select the number of digits for each operand using the pickers. Then tap one of the four operation buttons — Addition, Subtraction, Multiplication, or Division — to start.
The problem appears in standard written arithmetic layout. Tap each input box and enter a digit. For multiplication, fill in the partial products too. For division, work through the quotient, products, and remainders in order.
Tap "Check Answer" — a large circle means correct, an X means incorrect. If you got it wrong, correct your answer and try again. When you're ready, tap "Next Problem" for a fresh question.
"My kid uses this as a warm-up before homework. Since it's the same layout as the classroom exercises, it directly helps with schoolwork!"
"Long division was really hard for my daughter, but being able to practice each step — quotient, product, remainder — made the whole process click for her."
"I love that I can choose the digit count. I started with 1×1 and now I'm doing 3×2 multiplication. Practicing every day has made me so much faster at calculating."
