Question

Using convenient combinations, find the sum

(a) 873, 599, 127

(b) 6725, 3995, 3275​

Answer 1

Answer:

(a) 873 + 599 + 127  

(b) 6725 + 3995 + 3275

Step-by-step explanation:

(a) 873 +599 +127

Step 1: Arrange the 3 numbers in  a vertical column

Step 2:  Add the ones i.e. 3+9+7 =19 - so unit's place would have 9 and carry forward 1 to tenths place

Step 3:  Add 1+ 7 +9+2 = 19 - so place 9 at tenths place and carry forward 1

Step 4:  Add 1 + 8+ 5+ 1 =15

Step 5: The total answer will be 1599

(b)  6725 + 3995 +3275

Similarly,  do the calculation for each of units place, tens place, hundreds place and thousands place by arranging all three number vertically.

6725+3995+3275 = 13995
