find value of given numbers by suitable property
a) 308+563+222+937
b) 50 multiply 80 multiply 20 multiply 125
(a) 308 + 563 + 222 + 937
= 308 + 222 + 563 + 937
= (308 + 222) + (563 + 937) [associative law]
= 530 + 1500
= 2030
(b) 50 × 80 × 20 × 125
= (50 × 20) × (80 × 125) [Associative law]
= 1000 × 10000
=10000000
= 308 + 222 + 563 + 937
= (308 + 222) + (563 + 937) [associative law]
= 530 + 1500
= 2030
(b) 50 × 80 × 20 × 125
= (50 × 20) × (80 × 125) [Associative law]
= 1000 × 10000
=10000000
