Place the digits correctly and add 47 + 52 . H T O +

Given, 47 + 52 Now, write the numbers one below the other in the addition table. Write the ones digits in ones column and tens digits in tens column. H T O 4 7 + 5 2 First, add the numbers in ones place digits and then tens place digits. Add the ones: 7 + 2 = 9 ones Add the tens: 4 + 5 = 9 tens So, the sum is 99 . H T O 4 7 + 5 2 9 9 Therefore, the solution is shown above.

Place the digits correctly and add 62 + 38 . H T O +

Given, 62 + 38 Now, write the numbers one below the other in the addition table. Write the ones digits in ones column and tens digits in tens column. H T O 6 2 + 3 8 Add the number in ones place digits and then tens place digits. Add the ones: 2 + 8 = 10 ones Regroup 10 ones = 1 ten So, write 0 on the ones column and carry 1 to the tens column. Add the tens: 6 + 3 + 1 ( carry over ) = 10 tens Regroup 10 tens = 1 hundred carry 1 6 2 + 3 8 1 0 0 Therefore, the sum is 100 .

Place the digits correctly and add. 71 + 42 + 29 H T O +

Given, 71 + 42 + 29 Now, write the numbers one below the other in the addition table. Write the ones digits in ones column and tens digits in tens column. H T O 7 1 4 2 + 2 9 First, add the numbers in ones place digits and then tens place digits. Add the ones: 1 + 2 + 9 = 12 ones Regroup 12 ones = 1 ten + 2 ones So, write 2 in the ones column and carry over 1 to the tens column. Add the tens: 7 + 4 + 2 + 1 ( carry over ) = 14 tens Regroup 14 tens = 1 hundred + 4 tens carry 1 7 1 4 2 + 2 9 1 4 2 Hence, the sum is 142 .
