In some cases the Distributive Property of Multiplication over Addition or Distributive Property of Multiplication over Subtraction can be used to obtain an answer quickly. Represent the following operations using one of the distributive properties and also
give the answer.
801 ¡ñ 30 + 4 ¡ñ 30
65 ¡ñ 20 ¨C 5 ¡ñ 20

for the first one I assume they want you to factor out ¡ñ 30 and add 801+4
for the second, I assume they want you to first factor out ¡ñ 20 then do the combinationnot 100% sure. 
a) 801 ¡ñ 30 + 4 ¡ñ 30
b) 65 ¡ñ 20 ¨C 5 ¡ñ 20
Just a dark circle in between each number
801 30 +4 30
65 20 5 20
