Anzan Expert vs =42

Ever find that "6 + 9" is easy, but "7 + 9" feels tricky? Do you struggle with certain number combinations? I did! As the author of this app, I used to find combinations involving 8 or 9 particularly challenging. I also found it difficult to quickly calculate prices while shopping. That's why I created this flash calculation app – to improve my own mental math skills! And while developing and testing it, I've already noticed a real improvement in my addition skills. I'm confident you'll see a boost in your own mental math abilities too! I hope you have fun and enjoy your challenges! HOW TO US Numbers flash on the screen at a set interval. Add them up in your head! STAGES There are 20 stages, each combining one of 5 different digit lengths (1 to 5 digits) with one of 4 flash intervals (6, 3, 1, and 0.5 seconds). The most challenging stage is 5 digits with a 0.5-second interval – a true test of your skills! If you ever reach that level, you'll be a real "expert"! Each stage has a unique name. - 1 digit, 6-second interval: "Shell" stage - 1 digit, 3-second interval: "Prawn" stage - 1 digit, 1-second interval: "Turtle" stage and so on... EXPERT MEDALS AND LEVELS Earn an expert medal for each stage by answering correctly 5 times in a row at that stage. Your current level is determined by the highest-level stage where you've earned a medal. How far can you go? Find out now!

A quiet three minutes with your kid. =42 picks tonight's twelve multiplication facts from where they're shakiest, then steps back — you read each fact, listen to the answer, swipe. That's the whole app. WHY IT'S DIFFERENT We pick the queue, not you. A small spaced-repetition scheduler weights what's wrong-most-recent first, then what's never-yet-seen, then a handful of facts they've already learned, so practice is never empty. After tonight, the deck restocks itself for tomorrow. The kid never sees a score. Each card is just the next question. When they miss, the fact comes back tomorrow. No streaks, no stars, no sad faces — just the gradual feeling of "I know more than I did last week." THE LOOP → Open =42. Tonight's twelve facts are already chosen. → Read the fact: "Six times seven?" → They answer. → Swipe right if they knew it, left if they missed it. → After twelve facts: "9 of 12. Sharper." and you're done. About three minutes a session. CALMLY BUILT — Coverage map — an 11×11 grid colored by mastery, so you can see which corner of the table they own. — Practice calendar — every session counted, no gamification, just your record. — Optional voice — flip the speaker icon to have the app read each fact aloud (off by default, respects your phone's silent switch). — Long-press to drill — hold any fact in the coverage map and tonight's session starts with it. PRIVACY Everything stays on your device. No account, no sign-in, no kid profile in the cloud. The only data we send out is anonymous usage analytics and crash diagnostics — both opt-out at the OS level. Made for parents and grandparents who'd rather sit beside their kid than hand them a tablet. Designed for ages 7+ working through times tables; the parent stays in control of every session.
