Place Value Chart: Finding Components of 813 Using Hundreds, Tens, and Units

To solve this problem, we need to convert the number expressed through its individual digits for hundreds, tens, and units into its complete form by following these steps:

• Step 1: Identify the digits provided in the table: Hundreds $H = 8$, Tens $T = 1$, Units $U = 3$.
• Step 2: Recall the formula for constructing a number from its digit places: $H \times 100 + T \times 10 + U$.
• Step 3: Plug these values into the formula:
  $8 \times 100 = 800$
  $1 \times 10 = 10$
  $3 \times 1 = 3$.
• Step 4: Add these values together to find the number:
  $800 + 10 + 3\ = 813$.

Therefore, the addition exercise that results in 813 is $800 + 10 + 3 = 813$.
