Answer:
WE KNOW THAT, IN BODMAS
B - BAR
O - OF
D - DIVIDE
M - MULTIPLICATION
A - ADDITION
S - SUBTRACTION
1. 5{(-6)+(12÷4)}
= 5{(-6)+3}
= 5×(-3)
= (-15)
2. 10- {56÷(-16+9)}
= 10- {56÷(-7)}
= 10-(-8)
= 10 + 8
= 18
3.(-6)- {(-28)÷(-7)}
=(-6)- 4
= (-10)
4. 8- {12-(9- 【bar 】7-4)}
= 8 - {12-(9-3)}
= 8 - {12-6}
= 8 - 6
= 2
5. 11-[(-8)-{10-(9-【bar】7-4}]
= 11- [ (-8)- { 10-( 9-3)}]
= 11- [ (-8) - { 10 - 6}]
= 11- [ (-8) - 4]
= 11- ( - 12)
= 11 + 12
= 23
6. (-9)-[(-5) - {11-(8- 【bar】5-2)}]
= (-9) -[(-5) - {11-(8-3)}]
= (-9) - [(-5)- { 11-5}]
= (-9) - [(-5)-6]
= (-9) - (-11)
= (-9) + 11
= 2
7. 10-[8- {11+30÷(4 - 【bar】5-7)}]
= 10-[8- { 11+30÷(4-((-2))}]
= 10-[8- { 11+30÷(4+2)}]
= 10-[8- { 11+30÷6}]
= 10-[8- {11+5}]
= 10-[8-16]
= 10-(-8)
= 10+8
= 18
