Solve the Addition Problem: Finding the Sum of 26 + 19

To find the sum of the numbers $26$ and $19$, we perform the following step-by-step arithmetic calculation:

• Step 1: Arrange the numbers in a vertical column for addition:
  $\phantom{+1}26$
  $+\phantom{1}19$

• Step 2: Start adding from the unit column (right to left). Add the digits in the ones column:

  • 6 (from 26) + 9 (from 19) = 15. Write down 5 and carry over 1 to the tens column.

• Step 3: Move to the tens column and add:

  • 2 (from 26) + 1 (from 19) + 1 (carry) = 4, write down 4.

Thus, the sum of $26$ and $19$ is $45$.

Therefore, the correct answer is $45$.
