What is Addition?

Addition is a fundamental mathematical operation where two or more numbers, quantities, or objects are combined to find their total or sum. The symbol used for addition is the plus sign (+).

For example, in the expression 3 + 4, the numbers 3 and 4 are added together to give a sum of 7. Addition is a basic concept in arithmetic, used in everyday calculations like adding money, counting items, or combining measurements.

Addition Worksheets: Practice Questions with Solutions

Question 1: Add the numbers: 5 + 8.

Solution:

To solve 5 + 8, you just need to combine the two numbers.

1. Start with the number 5.
2. Now, add 8 to it by counting up from 5.
   • After 5 comes 6, 7, 8, 9, 10, 11, 12, 13.

It’s like having 5 apples and getting 8 more apples. Now you have 13 apples in total!

We can also use the normal method as following as well.

Question 2: Solve the following: 234 + 567.

Solution:

Let’s solve 234 + 567 step by step:

1. Start by adding the numbers in the one's place:
   • 4 + 7 = 11
     Write down the 1 and carry over the 1 to the next column (the tens place).
2. Now, add the numbers in the tens place:
   • 3 + 6 = 9, plus the 1 you carried over makes 10.
     Write down the 0 and carry over the 1 to the next column (the hundreds place).
3. Finally, add the numbers in the hundreds place:
   • 2 + 5 = 7, plus the 1 you carried over makes 8.

Now, put all the numbers together: 234 + 567 = 801.

We can visualize these steps as follows:

Question 3: What is the sum of 4.5 and 3.25?

Solution:

Align the decimal points and add similar to non decimal numbers.

1. Start with the number 4.5.
2. Now add 3.25 to it. Line up the decimal points:
   • Start by adding the numbers after the decimal point: 0.5 + 0.25 = 0.75.
   • Now add the whole numbers: 4 + 3 = 7.

So, when you add 4.5 + 3.25, the answer is 7.75.

We can visualize these steps as follows:

Question 4: Add the fractions: 1/2 + 3/4.

Solution:

To add the fractions 1/2 and 3/4, follow these steps:

1. First, find a common denominator. The denominators are 2 and 4, and the lowest common denominator is 4.
2. Convert 1/2 to have the denominator of 4: 1/2 = 2/4
3. Now, add the two fractions: 2/4 + 3/4 = 5/4
4. 5/4 is an improper fraction, which means the numerator (top number) is larger than the denominator (bottom number). You can convert it into a mixed number: 5/4 = 1 \frac{1}{4}.

So, 1/2 + 3/4 = \bold{1 \frac{1}{4}} or 1.25.

Question 5: Find the sum: 1025 + 6789.

Solution:

To find the sum of 1025 + 6789, follow these steps:

1. Start by lining up the numbers:1025 + 6789
2. Add the digits starting from the right onecarry-overs place):
   • 5 + 9 = 14 (write down 4, carry over 1)
   • 2 + 8 = 10, then add the carry-over 1 to get 11 (write down 1,carry-over 1)
   • 0 + 7 = 7, then add the carry-over 1 to get 8
   • 1 + 6 = 7

So, 1025 + 6789 = 7814.

We can visualize these steps as follows:

Question 6: Calculate the sum of the following numbers: 99 + 99 + 99.

Solution:

To calculate the sum of 99 + 99 + 99, follow these steps:

1. Add the first two numbers:99 + 99 = 198
2. Now, add the third number to the result: 198 + 99 = 297

So, the sum of 99 + 99 + 99 is 297.

We can visualize these steps as follows:

Question 7: Add the negative numbers: −7 + (−3).

Solution:

To add the negative numbers −7 + (−3):

1. When you add two negative numbers, you combine them, but the result stays negative.
2. So, −7 + (−3) is like combining 7 and 3, but the result will be negative: (-7) + (-3) = -10

Since both numbers are negative, the result is −10.

We can visualize these steps as follows:

Question 8: Jane has 15 apples, and she buys 10 more. How many apples does she have now?

Solution:

Jane starts with 15 apples and buys 10 more.

To find out how many apples she has now, simply add the two numbers:

15 + 10 = 25

So, Jane now has 25 apples.

Question 9: Add: 3456+7890.

Solution:

To add 3456 + 7890, follow these steps:

1. Line up the numbers: 3456 + 7890
2. Add the digits starting from the right onecarry-overs place):
   • 6 + 0 = 6
   • 5 + 9 = 14 (write down 4, carry over 1)
   • 4 + 8 = 12, then add the carry-over 1 to get 13 (write down 3, carry over 1)
   • 3 + 7 = 10, then add the carry-over 1 to get 11 (write down 1,carry-overtenthr 1)

So, 3456 + 7890 = 11,346.

We can visualize these steps as follows:

Question 10: Add the following decimals: 0.75 + 1.5.

Solution:

To add the decimals 0.75 + 1.5, follow these steps:

1. Line up the decimal points:0.75 + 1.50 (Notice that we add a zero to 1.5 to make it easier to add).
2. Add the numbers:
   • Start with the hundredth place: 5 + 0 = 5
   • Then the place: 7 + 5 = 12, (write down 2, carry over 1).
   • Finally, the ones place: 0 + 1 = 1, plus the carry-over 1 makes 2.

So, 0.75 + 1.5 = 2.25.

We can visualize these steps as follows:
