Question

What is \[3-3\times 6+2\]?

Answer 1

Hint: We are given a mathematical expression and we have to compute its value. The given expression has multiplication operator, addition operator and subtraction operator. In order to find the value of the expression, we will follow an order to carry out the operations associated with the given operators. Firstly, we will carry out the multiplication operation from left to right then, we will carry out the addition and the subtraction operation left to right. After solving based on the above order, we will have the value of the given expression.

Complete step by step answer:
According to the given question, we are given a mathematical statement whose value we have to find. The given expression we have is,
\[3-3\times 6+2\]----(1)
The given expression has three arithmetic operators namely, multiplication operator, addition operator and subtraction operator.
In order to carry out the respective operation, we will follow an order in which the particular operator will carry out its operation. And solving which will give us the value of the expression.
Firstly, we carry out the multiplication operation in the given expression from left to right, we will have,
\[\Rightarrow 3-18+2\]----(2)
In the above equation (2), we got 18 as 6 multiplied by 3 is 18.
Next, we will carry out the addition operation from left to right, we will have the new expression as,
\[\Rightarrow -15+2\]----(3)
We got -15 in the above equation as, -18 when added to 3 gives -15.
Next, we will carry out the subtraction operator from left to right, the new expression we will have is,
\[\Rightarrow -13\]

Therefore, the value of the given expression is \[-13\].

Note: The operators cannot be randomly executed. A particular order is followed, else it will result in a different answer. For a hint regarding the order of operations, we can also recall the PEMDAS which stands for Parenthesis Exponential Multiplication Division Addition and Subtraction.
