What if I wanted to do LR Addition/Subtraction with rounding up while using the Math Palace Technique? Assuming that I have a long number and that, I have to carry over/borrow a lot of numbers.*The Math Palace Technique would come in handy for remembering all the numbers.*LR addition/subtraction with rounding up would come in handy too as I would avoid carrying over or borrowing too many numbers, which makes the problem even more difficult.When you use the MATH PALACE, do you consider rounding-up only when it’s needed? For example, if you were asked to calculate
503 401 – 398 972 = ???
How would you work out the answer? Would you round-up “398 972” while using your Mental Math Palace, making more palaces? or do you have any other method for doing that?
Have a nice day ahead
Best regards and thank you in advance
Yeah the Math Palace method might seem challenging at first but this is the same method being used by Memory Champions to remember 1000+ digit numbers in record time.If you are rounding up and calculating you can use 4 or 5 memory palaces if you want. You can use two additional memory palaces one for the rounded up number and another for the amount you rounded up by. But usually you can just remember the rounded up number without any memory palace and you don’t have to remember the original number you rounded up to do the calculation.Let us take the example 503,401 – 398,972 = ???We can round up 398,972 to 400,000. Amount rounded up is 1028.You don’t have to use the number 398,972 again in your calculation so you don’t have to use a math palace to remember 398,972.The new calculation is 503,401 – 400,000 + 1028.You use a math palace just to remember 503,401 and 1028 as they are the main numbers in the calculation.Hope this answers your question.
