6 + 7 = 13
20 + 70 = 90
100 + 300 = 400
The 400 + 90 + 13 = 503
Hi , 127+376=503 because 6 plus 7 equals 13 we leave 3 and we carry the 1 , 7 plus 2 equals 9 plus the one that we had before = 10 , we leave the 0 and we carry the 1 , finally 3 plus 1 equals 4 plus the one that we had before= 5 , giving us 503.
