**Example 1:**

2 + 22 + 222= ?

The result of the addition is 2 + 22 + 222 = 246

Shortcut steps:

**Step 1:** Take 2 Common and Replace all 2 with 1.

2( 1 + 11 + 111 )

**Step 2:** Count the number of digits in each number.

i.e, 1 = 1 (digit), 11 = 2 (digit), 111 = 3 (digit) and write down all digits together that is 123.

**Step 3:** Multiply 2 * 123 = 246.

The final result is 246.

**Example 2:**

6 + 66 + 666 + 6666 + 66666 = ?

The result of the addition is 6 + 66 + 666 + 6666 + 66666 = 74070.

Shortcut steps:

**Step 1:** Take 6 Common and Replace all 6 with 1.

6( 1 + 11 + 111 + 1111 + 11111 )

**Step 2:** Count the number of digits in each number.

i.e, 1 = 1 (digit), 11 = 2 (digit), 111 = 3 (digit), 1111 = 4 (digit), 11111 = 5 (digit) and write down all digits together that is 12345.

**Step 3:** Multiply 6 * 12345 = 74070.

The final result is 74070.

**Example 3:**

8 + 88 + 888 + 8888 + 88888 + 888888 = ?

The result of the addition 8 + 88 + 888 + 8888 + 88888 + 888888 = 987648.

Shortcut steps:

**Step 1:** Take 8 Common and Replace all 8 with 1.

8( 1 + 11 + 111 + 1111 + 11111 + 111111 )

**Step 2:** Count the number of digits in each number.

i.e, 1 = 1 (digit), 11 = 2 (digit), 111 = 3 (digit), 1111 = 4 (digit), 11111 = 5 (digit), 111111 = 6 (digit) and write down all digits together that is 123456.

** Step 3:** Multiply 8 * 123456 = 987648.

The final result is 987648.

**Example 4:**

9 + 99 + 999 + 9999 + 99999 + 999999 + 9999999 = ?

The result of the addition 9 + 99 + 999 + 9999 + 99999 + 999999 + 9999999= 11111103.

Shortcut steps:

**Step 1: **Take 9 Common and Replace all 9 with 1.

9( 1 + 11 + 111 + 1111 + 11111 + 111111 + 1111111 )

**Step 2:** Count number of digits in each number.

i.e, 1 = 1 (digit), 11 = 2 (digit), 111 = 3 (digit), 1111 = 4 (digit), 11111 = 5 (digit), 111111 = 6 (digit), 1111111 = 7 (digit) and write down all digits together that is 1234567.

**Step 3:** Multiply 9 * 1234567 = 11111103.

The final result is 11111103.
