Final answer:
The sum of the numbers 29, 63, 67, and 30 is 189, which is calculated by adding the numbers in pairs first and then combining the results.
Step-by-step explanation:
To find the sum of each set of numbers: 29, 63, 67, 30 without using a calculator, you can add them in pairs to make the addition easier. Adding the first two numbers, 29 + 63 equals 92. Combining the next two numbers, 67 + 30 equals 97. Adding these two results together, 92 + 97, gives us a total sum of 189. Therefore, the sum of the numbers 29, 63, 67, and 30 is 189.
