Let's solve these basic addition problems step by step:
30 + 2 = 32 Adding 30 and 2 gives us 32.
40 + 3 = 43 When we add 40 and 3, the result is 43.
40 + 1 = 41 The sum of 40 and 1 is 41.
30 + 3 = 33 Adding 30 and 3 results in 33.
20 + 1 = 21 When 20 and 1 are added together, we get 21.
20 + 2 = 22 The sum of 20 and 2 is 22.
These simple addition problems help build the foundation for understanding basic arithmetic concepts. To find the sum, just combine the two numbers together by counting additional units from the first number.
