Question

Evaluate the value of the expression :

6 - 2 + 10 % 4 + 7

Answer 1

Explanation:

to the precedence order of comp signs. first % is solved. then + and -. 6-2+10%4+7.

6-2+2+7

4+8

13.

Answer 2

6 - 2 + 10 % 4 + 7 = 13.

• We can evaluate this expression with the help of operator precedence. Operator precedence decides the order in which terms may be evaluated. Certain operators have lower precedence than other operators.

• For example, the multiplication operator has higher precedence than the addition operator and subtraction operator.

• 6 - 2 + 10 % 4 + 7. Since modulus operand has a higher priority than + and -, so modulus operator would be solved first.

       ⇒   10 % 2 = 2.

       ⇒   Now, we have the equation,

       ⇒   6 - 2 + 2 + 7.

• Now, + and - have the same precedence, hence now we can evaluate the expression from left to right.

       ⇒   (6 - 2) + 2 + 7

       ⇒   4 + 2 + 7

       ⇒   13.

Hence, 13 is the answer of expression  6 - 2 + 10 % 4 + 7.
