### Example Question #41 : How To Add

What is the standard form for seven hundred thousand, nine hundred and forty-seven?

Explanation:

Seven hundred thousand is equal to 700,000.

Nine hundred is equal to 900.

Forty-seven is equal to 47 .

Thus, 700,947 is the correct answer.

### Example Question #42 : How To Add

Find the sum of the following two fractions:

Explanation:

When adding two fractions, you first need to make their denominators match. Find the least common multiple of the two denominators, then convert both fractions so that they both share that denominator. The least common multiple of  and  is , so that will be the new denominator. Convert  into  by multiplying its numerator and denominator by , and convert  into  by multiplying its numerator and denominator by . Then add together the converted fractions. , so  is the correct answer.

### Example Question #43 : How To Add

Evaluate the following expression:

Explanation:

If you’re having trouble, follow the following steps.

First, take the first two numbers and add them together.

Then, take the sum from the operation above and add it to the third number. You can repeat this process (i.e. only adding two numbers at a time, and then adding the next number to the sum) as many times as is necessary.

### Example Question #44 : How To Add

Evaluate the following expression.

Explanation:

If you’re having trouble, follow the following steps.

First, take the first two numbers and add them together.

Then, take the sum from the operation above and add it to the third number. You can repeat this process (i.e. only adding two numbers at a time, and then adding the next number to the sum) as many times as is necessary.

### Example Question #45 : How To Add

Evaluate the following expression.

Explanation:

If you’re having trouble, follow the following steps.

First, take the first two numbers and add them together.

Then, take the sum from the operation above and add it to the third number.

You can repeat this process (i.e. only adding two numbers at a time, and then adding the next number to the sum) as many times as is necessary.

### Example Question #46 : How To Add

Evaluate the following expression.

Explanation:

If you’re having trouble, follow the following steps.

First, take the first two numbers and add them together.

Then, take the sum from the operation above and add it to the third number.

You can repeat this process (i.e. only adding two numbers at a time, and then adding the next number to the sum) as many times as is necessary.

### Example Question #47 : How To Add

Explanation:

In order to solve this problem, rewrite the problem vertically, making sure to align or line up the decimal point. Remember to annex zeroes where necessary. In this problem you would annex one zero after the 2, thus making the decimal 34.20, and because 9 is a whole number it is represented as 9.00 as a decimal.

Adding from right to left we get the following. Recall that when a column adds to ten or greater we need to carry the tens digit to the next column.

### Example Question #48 : How To Add

Find the sum of 2,365 and 8,501.

Explanation:

To find the sum, we will add the two numbers together.  So, we line the numbers up by the place values starting from the right.  Then, we add from right to left. So, we start with

Now, we add the right most numbers.  We get

We add the next numbers.  We get

We add the next numbers.  We get

We write the comma.  We get

Now, we add the last numbers.  We get

Therefore, the final answer is 10,866.

### Example Question #49 : How To Add

Evaluate the Following Expression

Explanation:

If you’re having trouble, follow the following steps.

First, take the first two numbers and add them together.

Then, take the sum from the operation above and add it to the third number.

You can repeat this process (i.e. only adding two numbers at a time, and then adding the next number to the sum) as many times as is necessary.

### Example Question #50 : How To Add
