Calculate: Converting 2 Tens and 5 Units into Total Value

To solve the problem, let's go through the necessary steps:

• Step 1: Understand the terms "units" and "tens."
• Step 2: Convert the given terms into actual values.
• Step 3: Sum the values to find the total.

Now, let's address each step in detail:

Step 1: In the decimal system, "units" refers to the 'ones' place in a number, and "tens" refers to the 'tens' position. Each place value indicates a power of 10.

Step 2: Convert the terms into numerical values:
- "5 units" is simply $5$ because units are counted as single digit numbers from 0 to 9.
- "2 tens" means $2 \times 10$, which equals $20$.

Step 3: Add the values calculated in Step 2:
$5 + 20 = 25$

Therefore, the total when you add 5 units and 2 tens is $25$.
