Use _ to understand multi-digit addition.

Answer 1

To understand multi-digit addition using underscores (_), let's break down the process step by step.

Example Problem

Let's add the numbers 256 and 738.

Step-by-Step Process

1. Align the Numbers Write the numbers vertically, aligning them by place value (ones, tens, hundreds).

     256
   + 738
   

2. Add the Ones Column Start by adding the digits in the ones column (rightmost column).

   • 6 (from 256) + 8 (from 738) = 14
   • Write down 4 and carry over 1.

     256
   + 738
   ------
       4  (write 4, carry 1)
   

3. Add the Tens Column Next, move to the tens column. Add the digits plus any carry from the previous column.

   • 5 (from 256) + 3 (from 738) + 1 (carry) = 9

     256
   + 738
   ------
      94  (write 9 below, no carry)
   

4. Add the Hundreds Column Finally, add the hundreds column.

   • 2 (from 256) + 7 (from 738) = 9

     256
   + 738
   ------
    994  (write 9 below)
   

Final Result

Combine all the digits you've written down:

  256
+ 738
-----
  994

Thus, 256 + 738 = 994.

Summary

To perform multi-digit addition:

• Align the numbers by place value.
• Add starting from the rightmost column to the left, carrying over as necessary.
• Write down each answer as you go.

This method ensures accuracy and helps in visualizing the addition process.
