Question

I have maths home work from school so please help me find the value question a. ( 3+4+7) ×2 b. (1/2)-3 c. (-3) -2

Answer 1

Answer

A=28 . B=-5/2 . C=6

Answer 2

• We have to evaluate the above expression by using the given data.

           Given data:-

              $a) (3+4+7)\times2.\\b)(\frac{1}{2} )-3.\\c)(-3)-2.$

         To find:- Value of above expression.

         Solution:-

• To solve the above equation we will follow the BODMAS rule.

• BODMAS is an order of mathematic operations.

• BODMAS rule is to be followed while solving expressions in mathematics.

       It stands for,

          B= bracket

           O= order of power or rules

           D= division

           M= multiplication

           A= addition

           S=subtraction

         Therefore,

      a)

          $(3+4+7)\times7\\\Rightarrow 14\times 7\\\Rightarrow 98.$

    b)

          $(\frac{1}{2})-3\\\Rightarrow -\frac{5}{2}\\\Rightarrow -2.5 .$

     c)

         $(-3)-2\\\Rightarrow -5.$
