Practice: Quick Math

Mental Arithmetic Trainer

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Drill addition, subtraction, multiplication & division until every calculation feels instant. Preset levels or custom ranges, carrying & borrowing. Light/dark mode. Mental arithmetic isn't something you learn once — it's something you build through repetition. This app gives you a near-infinite supply of problems, letting you practice until any calculation feels effortless. Train with targeted drills for addition, subtraction, multiplication, and division. Focus on the operations that trip you up most, and go from uncertain to fluent. Built-in difficulty presets mean you can open the app and start immediately — no setup required. When you're ready to fine-tune, full customization is available: toggle carrying for addition, borrowing for subtraction, and set the exact number ranges for multiplication and division to suit your current skill level. The interface supports both light and dark mode, so it's comfortable to use anytime, anywhere. Multi-language support removes any language barrier to practice.
