Subtraction of numbers up to 10 000 000 without regrouping and by regrouping

Subtraction of numbers up to 10,000,000 without regrouping and by regrouping

When subtracting numbers, remember to consider the place value of each digit in the number. Start by subtracting ones, followed by tens, hundreds, thousands up to the highest place value of the given numbers. Also, you can subtract the numbers when arranged horizontally or vertically by regrouping or without regrouping.

Subtracting numbers horizontally and vertically without regrouping

9 878 784 – 4 768 670 =

Solution

Use the following steps to subtract the given numbers horizontally:

Steps:

1. Subtract ones. 4 – 0 = 4. Write 4 in the ones place.

2. Subtract tens. 8 – 7 = 1. Write 1 in the tens place.

3. Subtract hundreds. 7 – 6 = 1. Write 1 in the hundreds place.

4. Subtract thousands. 8 – 8 = 0. Write 0 in the thousands place.

5. Subtract ten thousands. 7 – 6 = 1. Write 1 in the ten thousands place.

6. Subtract hundred thousands. 8 – 7 = 1. Write 1 in the hundred thousands place.

7. Subtract millions. 9 – 4 = 5. Write 5 in the millions place.

9 878 784 – 4 768 670 = 5 1 1 0 1 1 4

Therefore, 9 878 784 – 4 768 670 = 5 110 114.

Example

5 7 6 5 8 6 0 ‒ 3 4 5 3 7 6 0

Solution

To subtract numbers vertically without regrouping, follow the same steps as for horizontal subtraction. That is,

5 7 6 5 8 6 0 ‒ 3 4 5 3 7 6 0 2 3 1 2 1 0 0

Therefore, the answer is 2 3 1 2 1 0 0
