**Add and subtract whole numbers up to millions:**

This is basic topic for the students who are in primary level. Here we are going to learn how to add and subtract whole numbers.

How to add and subtract whole numbers ?

When we add two or more whole numbers, first we have to line up the numbers based on the number of digits. We have to perform addition or subtraction from ones digit.

**Example 1 :**

Add 2489, 9605 and 3814

**Solution :**

Hence, 2,489 + 9,605 + 3,814 = 15,908

**Example 2 :**

Add 5806, 1068 and 8320

**Solution :**

Hence, 5,806 + 1,068 + 8,320 = 15,194

**Example 3 :**

Add 7957, 6438 and 4539

**Solution :**

Hence, 7957 + 6438 + 4539 = 18934

**Example 4 :**

Add 8534, 5879 and 6261

**Solution :**

Hence, 8534 + 5879 + 6261 = 20674

**Example 5 :**

Add 8534, 5879 and 6261

**Solution :**

Hence, 2006 + 2430 + 4231 = 8667

**Example 6 :**

Subtract 8534 from 10986

**Solution :**

Always we have to perform addition or subtraction from ones digit.

**Step 1 :**

By subtracting 4 from 6 we get 2.

**Step 2 :**

By subtracting the tens digit 3 from 8 we get 5.

**Step 3 :**

By subtracting the hundreds digit 5 from 9 we get 4.

**Step 4 :**

Since 5 is lesser than 8, we need to borrow one from the ten thousand digit. So, 5 will become 15 and subtract 8 from this 15.

Hence, 10986 - 8534 = 17,452

**Example 7 :**

Subtract 3907 from 4210

**Solution :**

Hence, 4210 - 3907 = 303

**Example 8 :**

Subtract 13396 from 15449

**Solution :**

Hence, 15449 - 13396 = 2053

**Example 9 :**

Subtract 10243 from 14807

**Solution :**

Hence, 14807 - 10243 = 4564

**Example 10 :**

Subtract 110262 from 253089

**Solution :**

Hence, 253089 - 110262 = 142827

**Example 11 :**

Subtract 11026 from 25089

**Solution :**

Hence, 25089 - 11026 = 14063
