• First add the digits in the unit place.

• If the above addition is greater than or equal to 10 then write the unit

place (ones place) digit below and tens place digit carry forward.

• Place the carry forward digit on the top of tens digit.

• Finally add all the three numbers.

• The answer may be two digit or three digit.

Here 58 is a two digit number so write the numbers 5 and 8 according to their place values. So 5 is below tens (T) place and 8 is below ones place (O). The second number is 23 , which is also a two digit number so write it according to its place values.

T O(1) 5 8 + 2 3 ______ 8 1 |

Write 78 and 22 according to their place value. Then add unit digit

(8 + 2= 10) as this answer is two digit so from that write 0 below the line in unit place column. Write Tens digit (1) below 'T' and above 7. Add all the three numbers ( 1 + 7 + 2 = 10). So the answer is 100.

T O(1) 7 8 + 2 2 ______ 1 0 0 |

T O(1) 9 8 + 4 2 ______ 1 4 0 |

T O8 4 + 7 6 ______ |
T O8 8 + 2 8 ______ |
T O2 4 + 5 9 ______ |
T O6 2 + 6 9 ______ |
T O8 4 + 2 6 ______ |

T O1 7 + 2 9 ______ |
T O8 4 + 1 8 ______ |
T O3 8 + 4 9 ______ |
T O1 5 + 4 7 ______ |
