**5 Tricks for Mathematics**

Here are 5 fast math
strategies students (and adults!) can use to do math in their heads. Once these
strategies are mastered, students should be able to accurately and
confidently solve math problems that they once feared solving.

**1. Adding large numbers**

Adding large numbers just
in your head can be difficult. This method shows how to simplify this process
by making all the numbers a multiple of 10.

**Here is an example:**

**644 + 238**

While these numbers are
hard to contend with, rounding them up will make them more manageable. So, 644
becomes 650 and 238 becomes 240.

Now, add 650 and 240
together. The total is 890. To find the answer to the original equation, it
must be determined how much we added to the numbers to round them up.

650 – 644 = 6 and 240 – 238
= 2

Now, add 6 and 2 together
for a total of 8

To find the answer to the
original equation, 8 must be subtracted from the 890.

890 – 8 = 882

So the answer to 644 +238
is 882.

**2. Subtracting from 1,000**

Here’s a basic rule to
subtract a large number from 1,000: Subtract every number except the last from
9 and subtract the final number from 10

**For example:**1,000 – 556

Step 1: Subtract 5 from 9 =
4

Step 2: Subtract 5 from 9 =
4

Step 3: Subtract 6 from 10
= 4

The answer is 444.

**3. Multiplying 5 times any number**

When multiplying the number
5 by an even number, there is a quick way to find the answer.

**For example, 5 x 4 =**

Ø Step
1: Take the number being multiplied by 5 and cut it in half, this makes the
number 4 become the number 2.

Ø Step
2: Add a zero to the number to find the answer. In this case, the answer is 20.

5 x 4 = 20

When multiplying an odd
number times 5, the formula is a bit different.

For instance, consider 5 x
3.

Ø Step
1: Subtract one from the number being multiplied by 5, in this instance the
number 3 becomes the number 2.

Ø Step
2: Now halve the number 2, which makes it the number 1. Make 5 the last digit.
The number produced is 15, which is the answer.

5 x 3
= 15

**4. Division tricks**

Here’s a quick way to know
when a number can be evenly divided by these certain numbers:

Ø 10 if
the number ends in 0

Ø 9 when
the digits are added together and the total is evenly divisible by 9

Ø 8 if
the last three digits are evenly divisible by 8 or are 000

Ø 6 if
it is an even number and when the digits are added together the answer is
evenly divisible by 3

Ø 5 if
it ends in a 0 or 5

Ø 4 if
it ends in 00 or a two digit number that is evenly divisible by 4

Ø 3 when
the digits are added together and the result is evenly divisible by the number
3

Ø 2 if
it ends in 0, 2, 4, 6, or 8

**5. Multiplying by 9**

This is an easy method that
is helpful for multiplying any number by 9. Here is how it works:

**Let’s use the example of 9 x 3.**

**Step 1**: Subtract 1 from the number that is being multiplied by 9.

3 – 1 = 2

The number 2 is the first
number in the answer to the equation.

**Step 2**: Subtract that number from the number 9.

9 – 2 = 7

The number 7 is the second
number in the answer to the equation.

So, 9 x 3 = 27
