Calculate the sum of all possible two-digits numbers using the digits 3 and 4?
33 + 34 + 43 + 44 = 154
To calculate the sum of all possible two-digit numbers using the digits 3 and 4, we can consider all the combinations of these digits.
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.
1. Place 3 in the tens place and 4 in the ones place:
- The number formed is 34.
2. Place 4 in the tens place and 3 in the ones place:
- The number formed is 43.
To calculate the sum of these two numbers, we add them together:
34 + 43 = 77
Therefore, the sum of all possible two-digit numbers using the digits 3 and 4 is 77.
To calculate the sum of all possible two-digit numbers using the digits 3 and 4, we need to find all the combinations of these digits and then sum them up.
To start, let's list down all the possible two-digit numbers using the digits 3 and 4:
1. 34
2. 43
Now, we can sum these two numbers:
34 + 43 = 77
So, the sum of all possible two-digit numbers using the digits 3 and 4 is 77.
