Fill in the blanks:
(i) −2317×1835=1835×......
(ii)−38×−719=−719×......
(iii) 157×−2110×−56=......×−2110×−56
(iv) −125×415×(25−16)=−125×415×......
(i) −2317×1835=1835×−2317 [∵ commutative property, a×b=b×a]
(ii) −38×−79=−79×−38 [∵ commutative property, a×b=b×a]
(iii) (157×−2110)×−56=157×(−2110×−56) [∵ Associative property, a×(b×c)=(a×b)×c)]
(iv) −125×415×(25−16)=[−125×415×25]−[−125×415×16]
[∵ Distributive Property, a×b×(c−d)=a×b×c−a×b×d]
