What is the physical meaning of multiplication when we multiply two quantities in physics to get a single quantity? Eg. Mass * acceleration = force.

Multiplication of a quantity is a mathematical operation of repeated addition. It involves adding the same number to itself a certain number of times, represented by the multiplicand and the multiplier, to get the final product.
To multiply a quantity, you need to first identify the multiplicand and the multiplier. Then, you need to add the multiplicand to itself the number of times indicated by the multiplier. For example, 3 x 4 means adding 3 to itself 4 times, which would result in a product of 12.
The rules for multiplying a quantity are as follows: the product of any number and 0 is 0, the product of any number and 1 is the number itself, and the product of any number and -1 is the negative of the number. Also, when multiplying two numbers with the same sign, the product is positive, and when multiplying two numbers with different signs, the product is negative.
Multiplication and division of a quantity are inverse operations. While multiplication involves repeated addition, division involves repeated subtraction. In multiplication, the multiplier tells you how many times to add the multiplicand, while in division, the divisor tells you how many times to subtract the dividend.
Multiplication of a quantity is used in various real-life situations, such as calculating area and perimeter of shapes, finding the total cost of multiple items, and determining how many days or hours are in a given number of weeks or months. It is also used in science and engineering to calculate quantities such as speed, force, and power.
