Multiplication: Multiplication is one of the four basic arithmetic operations, representing repeated addition. It involves combining equal groups of numbers to find a total, with terms known as factors and the result called the product.
For example, 4 × 3 means adding 4 three times (4 + 4 + 4), which equals 12. Multiplication is essential in various mathematical concepts, including algebra, geometry, and data analysis. It is fundamental to real-world applications such as calculating areas, scaling quantities, and understanding rates. Mastery of multiplication forms the basis for more advanced math skills like division, fractions, and proportional reasoning.4×3=4+4+4=12
This can be visualized as combining equal groups. So, multiplication can be seen as determining how many objects are in a set of equal-sized groups.Key Terms in Multiplication:
Example
If you have 5 bags, and each bag contains 2 apples, you can multiply the number of bags (5) by the number of apples in each bag (2) to find the total number of apples: 5×2=10 Thus, you have 10 apples in total.Multiplier × Multiplicand = Product
The total number of objects in each group is the multiplicand. The number of equal groupings is the multiplier. The product of multiplier and multiplicand is called the product. Example: If Multiplier = 5 and Multiplicand = 8, then the product is: Product = 5 x 8 = 48A × B = B × A
For example: 2 × 3 = 3 × 2 = 6A × (B × C) = (A × B) × C
For example: 2 × (3 × 4) = (2 × 3) × 4 = 24A × (B + C) = (A × B) + (A × C)
For example: 4 × (2 + 3) = 4 × 2 + 4 × 3 → 20A × 1 = A
For example:A × 0 = 0
where A is any integer. For example: 9 × 0 = 0Also Read-

Description:
A multiplication of two positive integers yields a positive result. The result is negative when you multiply one positive integer by one negative integer, or vice versa. A positive integer is produced when two negative numbers are multiplied.× | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |

Q.1: If Shikha has 10 baskets and each basket has 5 apples. Then find the total number of apples Shikha has.
Sol: Number of baskets Shikha has = 10
Number of apples each basket has = 5 Total number of apples = (Number of baskets) × (Number of apples in each basket) = 10 × 5 = 50 Therefore, Shikha has 50 apples.Q.2: Sam brings 3 boxes of chocolates from the market. If each box contains 50 chocolates, then how many total chocolates did he has?
Solution: Number of boxes = 3
Number of chocolates in each box = 50 Total number of chocolates = 3 x 50 = 150 Hence, Sam has 150 chocolates.Q.3: Find the product of 13.99 × 10000.
Sol: 13.99 × 10000
= 139900.00 = 139900
