This document provides examples and instructions for addition problems with numbers up to hundreds. It begins with simple addition problems adding 1 or 2 numbers with answers up to 10. It then demonstrates adding without carrying over tens and ones places for problems like 44 + 32. Finally, it shows adding hundreds, tens, and ones places for problems such as 116 + 23 and 161 + 214. It concludes by instructing the reader to complete addition practice problems in their textbook.

24. Tens OnesAdd 44 and 32
Tens Ones
4 4
+ 3 2
________________
7 6
Add theones:
4 ones+ 2 ones
= 6 ones
Add thetens:
4 tens+ 3 tens
= 7 tens
So, 44+32=76

25. Hundreds Tens Ones
Add 116 and 23
Hundreds Tens Ones
1 1 6
+ 2 3

1 3 9
Add theones:
6 ones+ 3 ones
= 9 ones
Add thetens:
1 tens+ 2 tens
= 3 tens So, 116+23
=139Add thehundreds:
1hundred+ 0 hundred
= 1 hundred

26. Hundreds Tens Ones
Add 161 and 214
Hundreds Tens Ones
1 6 1 + 2
1 4

Add theones:
1 one+ 4 ones
= 5 ones
Add thetens:
6 tens+ 1 ten
= 7 tens So, 161+214
=375Add thehundreds:
