Give me effective tips to do maths calculations in mind

I personally feel my visualization of chess board and some opening calculations in mind, have boosted to do it with maths too.
But is there anything besides this you ppl would like to share?

You should train your memory well so that you can remember which pieces are where and which pieces have already been eaten. There are special memory training apps for this (by the way, Hikaru uses them too)

Drink cofee before

You're welcome, I'm glad my advice helped you

127 + 98 = ?
127 + 100 - 2 = 225

127 / 5 = ?
127 * 2 / 10 = 25.4

And other things of that sort)

The reason you can visualize chess positions is because you trained chess.

Just gotta do the same with math.

After recovering from the stroke I suffered while reading that sentence, I believe you are trying to say that your ability to calculate in chess has improved with your ability to calculate numbers. You may want to rethink that.

You must take your opponent into a deep dark forest where 2+2=5, and the path leading out is only wide enough for one.
