Ye trick basically 11 se multiply krne ki h Jese 55×3= 11×5×3 =11×15 15 ko 11 se × krne ke liye 1) pehle 15 ke 1 and 5 ko max door likho 2) beachme dono corner wali digits ko add krdo(1+5=6) toh ans ayega 1 6 5 Similarly 63×11= 693 Agar beachme add krne per >9 aye toh 1 carry krke likhe Jese 69×11= 6(15)9 yaha per 15 ka 1 carry me jayega 6 per toh solution hoga 759
It does.. you have to add the tens digit from sum to the first number leaving the ones digit from the sum in the middle 77x4= 7x4= 28 ….2+8=10…. 2+1 (from 10) = 308 88x7= 8x7= 56 ….5+6=11…. 5+1 (from 11) = 616
@@starblox0983 77X4= 7x4 = 28, 8+2 =10, you add 1 to 2 & write the ones (0) in the middle which makes the final answer 308 😅 at least this way works for both 77x4 and 88x7
this trick is applicable only when either the multiplicand or multiplier is divisable by 11 since neither 82 nor 4 is divisable by 11, this trick is not applicable
