Will your system applicable be to numbers under different bases?

AWESOME trick
Thank you, sir

[@johnryder1713]

Sorry sir I got 16X397 = 6352, but is it 6342 as you added 1000 from -324?

[@shaliniganesh8893]

Thanks sir

[@biranchinarayanmohapatra4491]

In 3rd sum of 409*391*397, the 2nd and 3rd line read 6352 in place of 6342, it is writing mistake, in 4th line it is 6342 (6352-10), 10 with two zeros, will be 1000, then proceed the subtraction.....

Sir Please tell me this 594*604*603. How to solve this type of problems...

[@modernsavyasachi2534]

Sir but in the first step i.e if +9 * +9 * -3 is there then how to do....

[@tonybarfridge4369]

You really lost me there, but I found that 497x498x503= 500^3 [125,000,000] - 505,000 + (-3 x -2 x +3)= 124,495,500+18. Why the 505,000 I don't know but just an observation sir. To put in Vedic notation:
5^3-1/5x100-5/5x100+18 -Does it make any sense? 😅
