Answer 2

Answer:

) 26 × (– 48) + (– 48) × (–36)

(– 48) [ 26 +(–36) ]

(– 48) × [-10]

= 480

(b) 8 × 53 × (–125)

53\times[8\times(-125)]

53\times\left(-1000\right)

=\ -53000

(c) 15 × (–25) × (– 4) × (–10)

15\times\left(-1000\right)\ =-15000

(d) (– 41) × 102

-41\times\left[100+2\right]

-41\ \times\ 100\ +\left[\left(-41\right)\times2\right]

-4100+\left(-82\right)\ \ =\ -4182

(e) 625 × (–35) + (– 625) × 65

625\times\left[\left(-35\right)+\left(-65\right)\right]

625\times\left(-100\right)\ \ =\ -62500

(f) 7 × (50 – 2)

7\times50-7\times2

350-14\ \ =\ 336
