My was of Adding
It is easier to add if you don't have too much information to handle at once. If you wanted to add how much
9,656 + 3,291 is
It would be easier if you got rid of the extra information. Usually I over estimate or ROUND. But I will show you how my mind works this out if I wanted to add it together:
9,000 + 3,000 = 12,000
Of course, there are more numbers. So if we want to get MORE ACCURATE we add some more numbers together:
600+200 = 800
So now we are at 12,800, and it is time for more numbers
50+90= 140
Now we have 12,940 (getting complicated. hehe). And:
6+1 = 7
I am guessing the answer is 12,947? Check it!!!
Usually I can add fast in my head this way. My mind sorta goes:
9,3... 12
6, 2... 8
...12,8
okay
5,9... 14... 140
plus 8(800 that is)...940
...12,940
6,1...7
12,940,7
12 thousand 9 hundred and 47!!!
NOW TRY THIS!!!:
6,302 + 7,297
13,5,9,9
9,656 + 3,291 is
