Answer 2

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

            Given data:- $a=1,b=2,c=3.$

            To find:- Value of above expression $2a+b-c.$

            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

Now put the value a,b, and c in the given equation we get,

           $2(1)+2-3\\=2+2-3\\=4-3\\=1.$

     Hence we will get the value is $1.$
