multiplication and division
Multiplication is a mathematical operation that combines equal groups to find a total. For example, if you have 3 groups of 4 apples each, you can find the total number of apples by multiplying 3 by 4, which equals 12. This operation is often represented by the symbol "×" or "*".
Division, on the other hand, is the process of splitting a number into equal parts. It answers the question of how many times one number can fit into another. For instance, if you have 12 apples and want to divide them into 4 equal groups, you would divide 12 by 4, resulting in 3 apples per group.
