What multiplication expression represents 7+7+7+7?
The Correct Answer and Explanation is :
The multiplication expression that represents ( 7 + 7 + 7 + 7 ) is ( 4 \times 7 ).
Explanation:
- Understanding Addition and Multiplication:
- Addition is the process of combining two or more quantities to get a total. In this case, you are adding ( 7 ) four times.
- Multiplication, on the other hand, is a way of simplifying repeated addition. When you multiply a number by another number, you are essentially adding that number to itself as many times as specified by the second number.
- Identifying the Components:
- In the expression ( 7 + 7 + 7 + 7 ), the number ( 7 ) is being added together four times.
- Here, ( 7 ) is called the multiplicand, which is the number being multiplied. The number ( 4 ) indicates how many times ( 7 ) is added together, which is known as the multiplier.
- Rewriting the Expression:
- To express the repeated addition as a multiplication expression, you can write it as:
[
7 + 7 + 7 + 7 = 4 \times 7
] - This indicates that you are taking the number ( 7 ) and adding it to itself four times.
- Calculating the Result:
- To find the total, you can calculate ( 4 \times 7 ):
[
4 \times 7 = 28
] - Thus, the expression ( 4 \times 7 ) not only simplifies the addition but also provides the total sum, which is ( 28 ).
- Conclusion:
- Multiplication serves as a more efficient means of computing repeated addition. Instead of writing out each ( 7 ) individually, ( 4 \times 7 ) conveys the same information in a concise manner. This relationship between addition and multiplication is fundamental in mathematics and serves as a basis for understanding more complex mathematical concepts.
