​

Answer 1

Answer:

33×(−1) = −3

(b) \left(-1\right)\times225\ =-225(−1)×225 =−225

(c) \left(-21\right)\ \times\ \left(-30\right)\ =\ 630(−21) × (−30) = 630

(d) \left(-316\right)\times\left(-1\right)\ =\ 316\(−316)×(−1) = 316 

(e) \left(-15\right)\ \times\ 0\ \times\ \left(-18\right)\ =\ 0(−15) × 0 × (−18) = 0

(f) \left(-12\right)\ \times\ \left(-11\right)\times10\ =\ 1320(−12) × (−11)×10 = 1320

(g) 9\ \times\ \left(-3\right)\ \times\ \left(-6\right)\9 × (−3) × (−6) 

9\times18\ =1629×18 =162

(h) \left(-18\right)\times\left(-5\right)\times\left(-4\right)(−18)×(−5)×(−4)

90\times\left(-4\right)\ =\ -36090×(−4) = −360

(i) \left(-1\right)\times\left(-2\right)\times\left(-3\right)\times4(−1)×(−2)×(−3)×4

2\times\left(-3\right)\times42×(−3)×4

-6\times4\ =-24−6×4 =−24

(j) \left(-3\right)\times\left(-6\right)\ \times\left(2\right)\times\left(-1\right)(−3)×(−6) ×(2)×(−1)

18\times2\times\left(-1\right)\18×2×(−1) 

18\times\left(-2\right)=-3618×(−2)=−36
