Still reciting multiplication tables and children\’s songs? The ones in India are faster than ours! Hurry and collect it for your children

While Chinese mothers are happy because their children can memorize multiplication tables and nursery rhymes, Indian children are already memorizing 19*19 multiplication tables! No wonder India has made such rapid progress in recent years. The Indian nine-nine table is memorized from 1 to 19 (→19×19 multiplication), but do you know how Indians mentally calculate the multiplication of numbers from 11 to 19? I suddenly realized it after reading the following content. It’s really amazing! Please try to figure out the answer below using mental arithmetic: 13 × 12 = ? (Multiplicand) (Multiplier) The Indians calculate it like this: Step 1: First add \”13\” and the single digit of the multiplier \”2\”, 13+2=15 Step 2: Then add the number 13 Multiply the answer of the first step by 10 (→ that is to say, add a 0 at the end) Step 3: Then multiply the single digit of the multiplicand \”3\” by the single digit of the multiplier \”2\” 2×3=6 Four steps: (13＋2)×10＋6=156 Just like this, you can quickly calculate the multiplication from 11×11 to 19×19 using mental arithmetic. This is really amazing! Let’s try to calculate: 14×13: (1) 14+3＝17 (2) 17×10＝170 (3) 4×3＝12 (4) 170+12＝18216×17: (1) 16+ 7＝23 (2) 23×10＝230 (3) 6×7＝42 (4) 230+42＝27219×19 (1) 19+9＝28 (2) 28×10＝280 (3) 9× 9＝81 (4) 280+81＝361 It’s really simple, right? Hurry up and take care of your children. You have too many skills to overwhelm your body!
