(4 - 9) - (-11 + 3)

(4 - 9) - (-11 + 3)

= (-5) - (-8)

= 3

(15 - 7) - (8 - 12) + (7 - 10)

(15 - 7) - (8 - 12) + (7 - 10)

= 8 - (-4) + (-3)

= 12 + (-3)

= 9

5(12 - 3) - (-8)

5(12 - 3) - (-8)

= 5(9) - (-8)

= 45 - (-8)

= 53

500

5[10 - (8 - 12)]

5[10 - (8 - 12)]

= 5[10 - (-4)]

= 5[14]

= 70
