Answer:

Consider the number:
105,724.
So, the digits for the period or group:
Thousands are 105 and ones are 724.

Answer:

We have to find the multiplication of . So Hence,

Answer:

We have to add the following numbers. Step 1: First we add ones digits (first column from the right). We get 20 means 2 tens and 0 ones. We write 0 ones in right column and write 2 in the tens column. Step 2: Add the digits in the tens column, including the regrouped 2. We get 23. 23 can be regrouped as 2 hundreds and 3 tens. We write 3 tens in tens column and write 2 in the hundreds column. Step 3: Add the digits in the hundreds column. We get 15. Step 4: Add the digits in the thousands column. Hence, the answer of addition will be 8530.
