How can u use parenthesis to simplify calculations

answer: sometimes in equations, its best to solve whatever is in the parenthesis. try using the method pemdas

p = parenthesis

e = exponets

m = multiply

d = divide

a = add

s = subtract

the topic of simplifying expressions which contain parentheses is really part of studying the order of operations, but simplifying with parentheses is probably the one part of the order of operations that causes students the most difficulty. this lesson is meant to provide a little extra in this area.

step-by-step explanation:

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
