Finding the Minimum Addition to Transform 34 into Whole Tens

To solve this problem, we'll follow these steps:

• Calculate the next multiple of ten greater than 34.
• Determine the difference between this next multiple of ten and 34.

Now, let's calculate:

The smallest multiple of ten greater than 34 is 40. Therefore, we need to calculate $40 - 34$.

The difference is $40 - 34 = 6$.

Therefore, the solution to the problem is $6$.
