Even in addition we tend to use our calculator or mobile phones since we don't have that much confidence in our Mental Computation Skills but let me give you some tips. Maybe it might not help you a lot but somewhat improve your skills in adding MENTALLY. Let's begin!
Let's consider adding 247 +78. This tip is very simple all you to do is to break down numbers in ones, tens, hundreds, thousands and so on. So let's break down the given. 240 + 7 next is 70 + 8. Add first larger number then the smaller one. 240 + 70 = 310, 8 + 7 = 15 then 310 + 15 = 325. For me this help me a lot because we can easily add numbers once they are multiple of 10 like 70 and 240 because we can think this a 7 and 24 then once we are done adding it we just simply add 0 to make it 210.
I hope this tip may help you but for me the most effective one to improve our mental math is consistency! Keep on practicing and exercising it. Thank you so much!
