Multiply by 5 as half of times 10: 5 × 46 is 460 ÷ 2 = 230. Ten percent is a tenth, so 15 % of 80 is 8 plus half of 8, which is 12. For 9 × 7, think 10 × 7 minus 7. Estimation questions train exactly this sense for size, and the statistics show which operation still costs you time. A DAY WITH RECHENFLOW In the morning, the daily challenge: ten questions, one attempt. At lunch, a 60-second sprint to chase your best score. In the evening, a relaxed round without timer or streak. Five minutes are enough, and the streak shows how often you kept it up. No ads. No subscription. No cloud account is needed to play or buy.
