Question

Find the following products, using distributive laws:

847 × 99

Answer 1

Distributive property of multiplication over addition states that a (b + c) = ab + ac
Distributive property of multiplication over subtraction states that a (b − c) = ab - ac
847 × 99
= 847 × (100 − 1)
= 847 × 100 − 847 × 1
= 84700 − 847
= 83853
