What is multiplication? Repeated addition, product, by, times, multiply
Answers
Answer:
Repeated addition is adding equal groups together. It is also known as multiplication. If the same number is repeated then, we can write that in the form of multiplication.
For example: 2 + 2 + 2 + 2 + 2
Here 2 is repeated 5 times, we can write this addition as 5 × 2.
Similarly, to solve a multiplication problem through repeated addition, we repetitively group and add the same number again and again to find the answer.
The result of a multiplication operation is called a product. The multiplication of whole numbers may be thought of as a repeated addition; that is, the multiplication of two numbers is equivalent to adding as many copies of one of them, the multiplicand, as the quantity of the other one, the multiplier.
Multiplication of literals obeys all operation of multiplication of numbers. In arithmetic, we studied multiplication as the repeated addition.
For example, 5 + 5 + 5 + 5 is called 4 times 5 and it is written as 4 × 5.
Similarly, if a is a literal, then a + a + a + a is 4 times a and is written as 4 × a.
Sometimes, the sign of multiplication is confused with the letter x. To avoid such as confusion we omit the sign of multiplication between a number and a literal or between two literals.
Thus, when there is no sign between a literal and a number of two literals, it is understand that the two are multiplied.
Thus, y + y + y + y + y = 5 × y = 5y
Similarly, the product of literals a and b is written as ab.It should be noted that the product of the type y × 4 is not written as y4. Conventionally, we written it as 4y.
