d) (-21) + [16+ (-13)] +(-5)
e) (-20) + (-4) + (-1) × (-8)
f) (-7) × (-15) + 3 + (-2) x 6
g) 100 X (-10) + [300 + {100 – (100 – 50)}]​

Answer 1

1)(-21)+[16-13]-5

 (-21)+3-5

 -21-5+3

  -26+3

 -23

2)(-20)+(-4)+(-1)*(-8)

   (-20)-4-1*(-8)

   -20-4-8

   -32

3)(-7)*(-15)+3+(-2)*6

   105+3-12

   108-12

    96

4)100*(-10)+[300+{100-(100-50)}]

 100*(-10)+[300+{100-50}]

  100*(-10)+[300+50]

  100*(-10)+350

   -1000+350

    -650
