Can you please tell me what TU means at the top of my sums eg., and do I put the sums answer in the circle between the sums and add the answer onto the next sums answer?
TU TU
23 15
16+ 0 17+

In order to understand what TU means and how to correctly solve the given problem, let's break it down step by step:
1. Understanding the abbreviation TU:
- TU stands for "Tens and Units."
- In this context, it refers to the place value of the digits in a number. The "Tens" place represents the digit in the tens position (e.g., 2 in 23), and the "Units" place represents the digit in the ones position (e.g., 3 in 23).
2. Solving the addition problem:
- Let's consider the first sum: 23 + 15.
- Start by adding the digits in the units place together: 3 + 5 = 8.
- Since we are working with TU, you write down 8 in the units place directly below the line.
- In this particular case, there are no digits in the tens place to add, so you write a 0 above the line in the tens place.
3. Adding the previous answer to the next sum:
- The question mentions adding the answer for the first sum onto the second sum's answer.
- In this case, you add 8 (the units place answer for the first sum) to the next sum, which is 17+.
- So the calculation would be 17 + 8 = 25.
- Write down the answer, 25, in the units place below the line.
- Since there is no additional digit in the tens place for the second sum, write a 0 above the line in the tens place.
Therefore, the completed sums would be:
TU TU
23 15
16+0 17+
8 25
