Question

1.(-3)+(-8)÷(-4)-2×(-2)
2.(-8)-[(-6)+2÷2-{8-(-3)+3}]
​

Answer 1

Answer:

1. (-3)+(-8)÷(-4)-2×(-2)

= (-3)+2-2×2

= (-3)+2-4

= (-1)-4

= -5

2. (-8)-[(-6)+2÷2-{8-(-3)+3}]

= (-8)-[(-6)+2÷2-{8-0}]

= (-8)-[(-6)+2÷2-8]

= (-8)-[(-6)+1-8]

= (-8)-[(-5)-8]

= (-8)-(-13)

= -21

Answer 2

$\large\sf\blue{❥Answer}$

1.

$\sf{( - 3) + ( - 8) \div ( - 4) - 2 \times ( - 2)}$

Divide -8 by - 4 to get 2

$\sf{⇒ - 3 + 2 - 2( - 2)}$

Add - 3 and 2 to get -1

$\sf{⇒ - 1 - 2( - 2)}$

Multiply 2 and - 2 to get -4

$\sf{⇒ - 1 - ( - 4)}$

The opposite of -4 is 4.

$\sf{⇒ - 1 + 4}$

Add -1 and 4 to get 3

$\sf{⇒3}$

Hence ,

Answer is 3

2

(-8)-[(-6)+2÷2-{8-(-3)+3}]

Divide 2 by 2 to get 1

⇒-8-[-6+1-{8-(-3)+3}]

Add -6 and 1 to get -5

⇒-8-[-5-{8-(-3)+3}]

The opposite of -3 is 3

⇒-8-[-5-{8+3+3}]

Add 8 and 3 to get 11

⇒-8-[-5-{11+3}]

Add 11 to 3 to get 14

⇒ -8-[-5-14]

Subtract 14 from -5 to get -19

⇒-8 -[-19]

The opposite of -19 is 19

⇒-8 +19

Add -8 and 19 to get 11

⇒11

Hence ,

Answer is 11
