Question

22 Find the value of
a) 8-[7-12 ] (b) - 15-75+200
1 125-93-27 (d) 8 -(-4+2)​

Answer 1

Answer:

(a) 8-[7-12] =8-[-5] = +13.

(b) -15-75+200=-90+200=110.

(c)1125-93-27=1032-27=1005.

(d)8-(-4+2)=8-(-2)=+10.

Answer 2

Answer:a)13

             b)110

             c)1005

             d)10

Step-by-step explanation:  

a) The question was: 8-[7-12]

    On subtracting the values on the brackets first,

    8-[-5]

    By taking [-5] out of the brackets,

    8+5=13

b) Question: -15-75+200

   By BODMAS Rule, performing addition first,

     -15+125=110

c)  Question:1125-93-27

     Taking values and operations according to our own convenience,

     1032-27=1005

d)  And the last question:8-(-4+2)

   By BODMASS ,

   8-(-2)

    8+2=10
