How do I improve mental math? I can't even multiply decimals in my head and barley basic numbers. Please help

Only Practice can improve that.

But where to start?

ah I don't know just do your class problems... more and more every time that's the only way you can become a good human calculator and do learn mathematical tables upto 20 though I don't do this stuff and I don't either recommend you to do but if you want to improve then you can start.

there is no way to improve your mental math other than practicing it out on paper; if your looking for convenient ways to spit out a number regardless of how the math is worked, there are "snake oils" for that online.

you start with knowing how to add and subtract; multiply and divide; log and exponent; and whatever other stuff there is to do :)

I had a problem with that too. I asked for help from a teacher and my parents. Even friends. I improved it by practicing problems out on paper. It took a while to master, but in time, I completed it. I remember in 5th grade, we had to do a sheet of 50 multiplication problems. We started out with 3 minutes, and by the end of the year, we'd have to do it in 45 seconds. I never really did great on it, but with some extra practice at home, I was able to complete all 50 in the time given of 45 seconds. PRACTICE PRACTICE PRACTICE :)

Thank you guys , I will do my best
