Addition of 6-digit numbers (without carrying)

1. Find the sum of 524163, 312805 and 120021

Steps I. Arrange the digits of the addends in columns. II. Add ones 3 + 5 + 1 = 9 III. Add tens 6 + 0 + 2 = 8 IV. Add hundreds 1 + 8 + 0 = 9 V. Add thousands 4 + 2 + 0 = 6 VI. Add ten thousands 2 + 1 + 2 = 5 VII. Add lakhs 5 + 3 + 1 = 9

The sum of 524163, 312805 and 120021 is 956989.

Addition of 6-digit numbers (with carrying)

2. Find the sum of 634957, 865241 and 358264 with carrying.

Steps I. Add ones. 7 + 1 + 4 = 12 ones = 1 ten 2 ones. Write 2 under ones, carry 1 to tens place. II. Add tens. 1 (carry up) + 5 + 4 + 6 = 16 tens = 1 hundred 6 tens. Write 6 under tens, carry 1 to hundreds place. III. Add hundreds. 1 (carry up) + 9 + 2 + 2 = 14 hundreds = 1 thousand 4 hundreds. Write 4 under hundreds, carry 1 to thousands place. IV. Add thousands. 1 (carry up) + 4 + 5 + 8 = 18 thousands = 1 ten thousand 8 thousands. Write 8 under thousands, carry 1 to ten thousand place. V. Add ten thousands. 1 (carry up) + 3 + 6 + 5 = 15 ten thousand = 1 lakh 5 ten thousands. Write 5 under ten thousands, carry 1 to lakhs place. VI. Add lakhs. 1 (carry up) + 6 + 8 + 3 = 18. Write 18 under lakhs.

Therefore, the sum of 634957, 865241 and 358264 is 1858462.
