3 a) 526 x 62 + 18 x 526 + 526 x 20
= 526 x (62+18+20) Distributive property of multiplication over addition
= 526 x 100
= 52600
b) 363 + 714 + 1637 + 286
= (363+1637) + (714 + 286).
= 2000 + 1000
= 3000
( NOTE : In sums like 3b. add the numbers in such a way that 0 is brought in the ones place of the sum. Then the sum becomes easier to add)
