154

To calculate the sum of all possible two-digit numbers using the digits 3 and 4, we need to find the sum of all possible combinations they can form.

The two-digit numbers can be formed by placing the digit 3 in the tens place and the digit 4 in the ones place, or vice versa.

So, we have the following possible two-digit numbers: 34 and 43.

To calculate their sum, we add them together:

34 + 43 = 77

Thus, the sum of all possible two-digit numbers using the digits 3 and 4 is 77.
