3. Add the product of (-16) and (-9) to the quotient of (-132) by 6.
4. By what number should (-240) be divided to obtain 16?
5. What should be divided by (-7) to obtain 12?
6. Evaluate:
(i) (-6) × (-15) (-5)
(ii) (-8) × (-5) 9
(iii) 9 (-12) x 10
(iv) (-75) x 8
(v) (-5) × (-5) (-5) ...... taken 5 times (vi) (-1)^(-1) (-1)
...... taken 25
7. Evaluate:
(i) (-16)x12 +(-16) x 8
(ii) 25 (-33) + 25 x (-17)
(iii) (-19) (-25)+(-19) (-15)
(iv) (-47) x 68-(-47) x 38
