1. Evaluate the following:
(i) (-7) x (-9) (-11)
(ii) (-5) x 7 x (-6) (-8)
(iii) (-1024) = 32
(iv) (-216) = (-12)
2. What will be the sign of the product if we multiply 39 negative integers and 98 positive
integers?
3. Use the sign >, < or = in the box to make the following statements true:
(i) (-15) + 38 D 27 + (-50)
(ii) (-13) x 0 (-5) O(-7) × (-6) x 14
(iii) (-18) = (-3) (-10) + (-15) + 31
(iv) (-5) × (-7) × (-10) (-1400) = (-4)
4. Is ((-45) = (-15)) = (-3) = (-45) = ((-15) = (-3))?
5. Simplify the following:
(i) (-7) + (-6) = 2 - {(-5) (-4) - (3 - 5)}
(ii) 11 - [7 - {5-3 (9-3-6)}].
