Hi,
You need to develop 3 calculation skills:
1) Learn how to multiply double-digit numbers (https://www.youtube.com/watch?v=6ndkkPZYJHo).
2) Learn how to work with zeros. The best way - always use 10^power instead of zeros
Example:
300x9000 = 3*10ˆ2 x 9*10ˆ3=3x9*10ˆ(2+3)=27*10ˆ5
Handwritten it looks not that complicated. If you get used to writing all the numbers that way, you will never lose zeros and all multiplications/divisions will be replaced with + or -.
3) Additionally, I suggest to learn how to make the division mentally:
Learn the division table up to 1/11 (i.e. 5/6 = 83.3%). It will help you calculate any percentage problems
Finally, use math tools (Mimir math for iOS, Math tool on Viktor Cheng website) to practice. Train, train, and train again
Good luck!
