When do you use order of operations and when do you use the distributive property?

Dec 21, 2014

REMEMBER IT THIS WAY BODMAS(Brackets off,division,multiplication,addition and subtraction)

The distributive law is used in situations like this

$a \left(b - c\right) = a b - a c$

(This is the distributive law of multiplication over subtraction)

$a \left(b + c\right) = a b + a c$

(This is the distributive law of multiplication over addition).

let me cite some eg.

${x}^{2} \left(2 {y}^{3} - 98\right) = {x}^{2} 2 {y}^{3} - 98 {x}^{2}$

$3 {x}^{2} \left(2 {y}^{3} + 1\right) = 6 {x}^{2} 2 {y}^{3} + 3 {x}^{2}$

HOPE THIS HELPS YOU
