The Power of Multiplying by Powers of 10

Multiplying by powers of 10 is an incredibly useful technique, particularly when dealing with large numbers or decimal values. By understanding the effect of shifting the decimal point, we can quickly determine the result of such multiplications. Consider the following examples:

Example 1:

To multiply 346 by 100, we simply shift the decimal point two places to the right. Therefore, 346 multiplied by 100 equals 34,600.

Example 2:

To multiply 5.32 by 1,000, we shift the decimal point three places to the right, resulting in 5,320.000.

The Distributive Property

The distributive property allows us to break down multiplication problems into smaller, more manageable parts. By distributing a number into its components, we can simplify complex calculations and reduce the chances of errors. Let’s explore this technique with two examples:

Example 1:

To multiply 26 by 14, we can break it down into (20 + 6) multiplied by 14. Applying the distributive property, we get (20 * 14) + (6 * 14) = 280 + 84 = 364.

Example 2:

To multiply 38 by 53, we can break it down into (30 + 8) multiplied by 53. Applying the distributive property, we get (30 * 53) + (8 * 53) = 1,590 + 424 = 2,014.

Multiplying by 11

Multiplying numbers by 11 can be simplified with a neat trick. To multiply a two-digit number by 11, all you need to do is add the two digits together and insert the resulting sum between the original digits. Let’s illustrate this with an example:


To multiply 63 by 11, add 6 + 3, resulting in 9. Place 9 between 6 and 3, giving you the answer of 693.

The Magic of Multiplying by 9

Multiplying numbers by 9 may seem challenging, but once you know the trick, it becomes a breeze. Here’s how it works:


To multiply 9 by any single-digit number, subtract 1 from the number to the left, and the result will be the tens digit. The complement to 9 of the original number is the ones digit. Let’s see this in action:

To multiply 9 by 7, subtract 1 from 7, resulting in 6 (tens digit). The complement to 9 of 7 is 2 (ones digit). Hence, 9 multiplied by 7 equals 63.

Squaring Two-Digit Numbers Ending in 5

When squaring two-digit numbers that end in 5, a simple trick can save you time. Follow these steps:


To square 35, take the first digit (3) and multiply it by the next consecutive digit (4). Append 25 to the result. Therefore, 35 squared is equal to (3 * 4) with 25 at the end, giving you 1,225.

Multiplying Large Numbers Using Partial Products

Multiplying large numbers can be daunting, but the technique of partial products can simplify the process. Here’s a step-by-step approach:

  • Step 1: Break down the numbers into smaller parts. For example, let’s multiply 456 by 123. Break it down into (400 + 50 + 6) multiplied by (100 + 20 + 3).
  • Step 2: Multiply each part individually. Start by multiplying the digits in the ones place, then the tens place, and so on. Multiply 400 by 100, 400 by 20, 400 by 3, and so on. Repeat this process for 50 and 6.
  • Step 3: Add up the partial products. Sum up the results obtained from multiplying each part. The final sum is the product of the two numbers.


To multiply 456 by 123, we break it down into (400 + 50 + 6) multiplied by (100 + 20 + 3).

Multiply the individual parts:

400 multiplied by 100 = 40,000

400 multiplied by 20 = 8,000

400 multiplied by 3 = 1,200

50 multiplied by 100 = 5,000

50 multiplied by 20 = 1,000

50 multiplied by 3 = 150

6 multiplied by 100 = 600

6 multiplied by 20 = 120

6 multiplied by 3 = 18

Add up the partial products:

40,000 + 8,000 + 1,200 + 5,000 + 1,000 + 150 + 600 + 120 + 18 = 56,888

So, 456 multiplied by 123 equals 56,888.

Multiplying Decimals

Multiplying decimals can be simplified by following a specific procedure. Here’s an example:


To multiply 3.2 by 4.5, ignore the decimals initially and multiply 32 by 45. This gives you 1,440. Now, count the total number of decimal places in both numbers (one in this case). Place the decimal point in the answer so that it has one digit to the left of the decimal point. The final result is 14.4.

Multiplication Tricks

Multiplying Fractions

Multiplying fractions can be made easier by canceling out common factors and reducing the fractions to their simplest form. Here are the steps:

  • Step 1: Multiply the top numbers (numerators) of the fractions.
  • Step 2: Multiply the bottom numbers (denominators) of the fractions.
  • Step 3: Simplify the resulting fraction by eliminating any shared factors.


To multiply 3/5 by 4/7, multiply the numerators (3 * 4) to get 12 and multiply the denominators (5 * 7) to get 35. Simplify the fraction by dividing both the numerator and denominator by their greatest common factor, which is 5 in this particular case. The simplified result is 12/35.
