Question

Identify operators (addition, subtraction, multiplication, division) in forming the following expressions and tell how the expressions have been formed: $3y - 5$

Answer 1

Hint: First we have to define what the terms we need to solve the problem are. First of all, we need to know about the operations which are used in the given problem,
The addition is the sum of two or more than two numbers, or values, or variables and in addition, if we sum the two or more numbers a new frame of the number will be found, also in subtraction which is the minus of two or more than two numbers.


Complete step-by-step solution:
Multiplying means repeated addition of a number. (which is the number of times addition) Multiplicand refers to the number that we multiply.
Let’s see this with an example; while multiplying the number $2 \times 5$ then the number $2$ is known as multiplicand and the number $5$ is known as the multiplier and division is the inverse function of the multiplication.
Hence by these operators; we only need the two operators to perform $3y - 5$
The first one is multiplication which is the multiplying $3 \times y$. The number $3$ is called the multiplicand and the number $y$ is called the multiplier. Three times of the function $y$
The second step is the subtraction operator; $5$ is subtracted from the above result;
Hence, we get $3y - 5$

Note: There is a condition in the subtraction, that in subtraction the greater number sign will stay constant example $2 - 3 = - 1$, three has the greater sign with negative thus the resultant answer is negative if suppose three is positive and two is negative then the resultant answer will be positive.
And in multiplication negative signs into negative also positive into positive signs only give the result as positive. Otherwise, any one of the terms is negative and positive the result is negative.
